Product Overview

The Schneider Electric MTE16N Circuit Breaker is listed as an industrial electrical protection device intended for use in electrical distribution and industrial power-control systems. Circuit breakers play an essential role in protecting electrical installations by interrupting current when abnormal operating conditions, such as overloads or short circuits, occur within their designed protection range.

In industrial environments, circuit protection is necessary to safeguard electrical conductors, connected equipment, distribution panels, and downstream loads. A correctly selected circuit breaker helps isolate an affected circuit and limits the potential consequences of electrical faults. Its effectiveness depends on the device’s rated current, operating voltage, interrupting capacity, trip characteristics, and coordination with the rest of the electrical system.

The MTE16N designation should be verified against the original nameplate or manufacturer documentation before procurement. Exact identification is particularly important for industrial circuit breakers because products with similar model designations may have different electrical ratings, frame sizes, trip units, mounting arrangements, and accessory configurations.

For this listing, the supplied physical dimensions are 322 × 228 × 277 mm, and the stated weight is 30 kg. These values can be used as preliminary product-listing information, subject to verification against the actual unit.

When selecting this product for a maintenance or replacement project, buyers should confirm the full catalog number, manufacturer identification, electrical ratings, pole configuration, trip-unit specifications, and mounting type. These details determine whether the breaker is suitable for the intended distribution panel and operating environment.

Technical Specifications

Important: Electrical ratings are intentionally left unconfirmed because the exact MTE16N designation could not be reliably matched to manufacturer documentation. Do not use this table as the basis for electrical installation or protection-device selection.

Function and Working Principle

A circuit breaker is designed to carry current under normal operating conditions and interrupt the circuit when a qualifying fault or abnormal current condition occurs. The precise operating mechanism and protection functions depend on the breaker’s design and installed trip unit.

1. Overload Protection

An overload occurs when a circuit carries more current than permitted for an extended period. Depending on the breaker’s design, a thermal or electronic protection mechanism detects the condition and initiates a trip.

Appropriate overload protection helps prevent excessive heating in conductors and connected equipment. The trip settings must be selected according to the conductor ratings, connected load, equipment requirements, and applicable electrical standards.

The specific overload characteristics of the MTE16N must be verified before it is used in an actual installation.

2. Short-Circuit Protection

A short circuit can cause a rapid increase in current, creating high thermal and electromagnetic stress on electrical equipment. A suitably rated circuit breaker interrupts the affected circuit when the fault current exceeds its protection threshold.

The breaker’s interrupting capacity must be sufficient for the prospective short-circuit current at the installation point. A device that cannot safely interrupt the available fault current is not an appropriate substitute, even if its physical dimensions or nominal current rating appear similar.

3. Circuit Isolation

Industrial circuit breakers can also provide a means of isolating electrical circuits for maintenance, depending on the device’s design and applicable isolation requirements.

Before servicing equipment, personnel must follow the site’s lockout and tagout procedures and verify that the circuit is de-energized. A breaker should not be assumed to provide every required isolation or safety function without confirming its specifications and installation.

4. Protection Coordination

Circuit breakers are often installed in coordinated protection systems containing upstream and downstream protective devices. Proper coordination helps limit the portion of an electrical installation affected by a fault.

Coordination depends on the protective devices’ trip curves, short-circuit ratings, settings, and the characteristics of the power system. It should be evaluated by qualified electrical personnel using the actual equipment data.

Role in Industrial Electrical Systems

Circuit breakers are fundamental components in industrial electrical distribution systems. They help protect feeders, distribution sections, machinery supplies, and other circuits against defined electrical fault conditions.

Main Distribution Panels

In a main or sub-distribution panel, a suitably selected breaker provides protection for a particular section of the electrical network. Its rating and interrupting capacity must match the electrical characteristics of that section.

For replacement applications, the engineer should check the original circuit design, available fault current, conductor sizing, and upstream protective devices before approving the replacement.

Industrial Machinery

Production equipment often contains motors, drives, control power supplies, heating elements, and auxiliary circuits. Circuit protection helps isolate faults that could otherwise damage wiring or connected equipment.

The breaker must be selected according to the specific load and the manufacturer’s protection requirements. Motor circuits may require additional consideration of starting current, overload protection, and coordination with contactors or variable frequency drives.

Electrical Control Cabinets

Control cabinets house the equipment used to distribute power and operate industrial automation systems. Circuit breakers can protect incoming supplies, branch circuits, and selected auxiliary loads.

Installation planning should account for the device’s physical dimensions, connection clearances, heat dissipation, and access for inspection or replacement.

Maintenance and Equipment Replacement

Industrial facilities may need replacement circuit breakers when installed equipment reaches the end of its service life or becomes damaged. In these situations, identifying the exact original model is essential.

A replacement must match the electrical and mechanical requirements of the application. A device should not be selected solely because it carries the same brand name or fits into the available space.

Industrial Applications

The application of the MTE16N depends on its verified electrical ratings and construction. The following are general applications for appropriately rated industrial circuit breakers rather than confirmed, model-specific approvals.

1. Industrial Power Distribution

Industrial facilities use circuit breakers to protect electrical distribution circuits supplying machinery, lighting, auxiliary services, and production areas.

Selection must account for the nominal system voltage, expected load current, prospective short-circuit current, and the coordination strategy used throughout the facility.

2. Manufacturing Equipment

Manufacturing systems may include processing machinery, assembly lines, material-handling equipment, and automated production cells. Circuit breakers provide protection for suitable electrical supplies within these systems.

The device’s rated current and trip characteristics must be compatible with the connected load and wiring.

3. Motor-Control Systems

Motor-control installations may use circuit breakers in conjunction with contactors, overload relays, soft starters, or variable frequency drives. The specific arrangement depends on the motor and the applicable protection design.

The selected breaker must be suitable for the available fault current and the requirements of the motor-control equipment. It should not be assumed that any general-purpose circuit breaker is automatically appropriate for motor protection.

4. Industrial Distribution Cabinets

Distribution cabinets require protective devices that fit the panel’s mechanical design and electrical ratings. The supplied dimensions of 322 × 228 × 277 mm may help with preliminary layout planning, but actual mounting dimensions and connection positions should be checked before installation.

Adequate access should be provided for conductor termination, inspection, testing, and maintenance.

5. Plant Maintenance and Spare-Parts Management

Industrial plants often maintain spare breakers to reduce downtime after equipment faults. An effective spare-parts strategy records the complete catalog number, electrical ratings, trip-unit details, accessories, and the installation location.

For the MTE16N listing, the exact model identification should be resolved before the item is designated as a direct replacement for an existing breaker.

Installation and System Integration

Circuit breaker installation must follow the manufacturer’s instructions, the electrical system design, and applicable safety standards. The following considerations are general guidance and do not replace model-specific installation documentation.

1. Verify the Product Identification

Check the manufacturer’s name, complete catalog number, serial or date information where applicable, and the ratings shown on the nameplate.

If the label reads MTE16N, compare it with the original equipment documentation or a manufacturer-approved catalog. Do not substitute specifications from a similarly named model without confirming that the products are identical.

2. Confirm Electrical Ratings

Before installation, verify at least the following:

• Rated operational voltage.
• Rated current and any adjustable current settings.
• Number of poles and circuit configuration.
• Rated short-circuit breaking capacity.
• Trip-unit type and protection functions.
• Applicable operating frequency and installation conditions.
• Compatibility with upstream and downstream protective devices.

These values must be established before the breaker is used to protect an energized circuit.

3. Check Mounting and Dimensions

The supplied dimensions are 322 × 228 × 277 mm. Confirm the physical dimensions of the actual device, including any removable accessories, operating mechanisms, and connection hardware.

The space required for installation may be greater than the basic body dimensions. Allow for conductor bending radius, terminal access, arc-related clearances where specified, and safe operation of the handle or operating mechanism.

4. Inspect Connections and Conductors

Use conductors, terminals, and connection hardware that comply with the manufacturer’s specifications. Check conductor size, material, termination method, tightening torque, and any required preparation.

Loose or unsuitable connections can cause localized heating, voltage drop, equipment damage, or fire hazards. All installation work should be performed by qualified personnel.

5. Coordinate Protection Settings

Where the breaker includes adjustable protection, settings should be established according to the approved protection study and the connected equipment’s requirements.

The settings should coordinate with upstream and downstream devices and provide the intended protection without causing inappropriate trips during normal operation.

No specific trip settings can be recommended for the MTE16N until its exact protection configuration is confirmed.

6. Perform Commissioning Checks

Before returning the circuit to service, qualified personnel should complete the checks required by the applicable installation and commissioning procedures.

These may include visual inspection, mechanical operation checks, verification of connections, protective-device testing, and confirmation that the device matches the approved design documentation.

Compatible System Components

The following components are commonly found in industrial circuit-protection installations. Their suitability for use with the MTE16N must be assessed against the verified breaker specifications.

The table describes possible system components, not a confirmed accessory list for the MTE16N. The exact accessory options and electrical interfaces must be checked against the product documentation.

Alternative Models and Replacement Considerations

The exact identity of MTE16N remains unconfirmed. A similar-looking or similarly named Schneider Electric breaker should not be treated as an equivalent without a technical comparison.

A valid replacement must match the electrical requirements and the mechanical configuration of the original installation.

When a direct replacement is unavailable, a qualified electrical engineer should evaluate alternative models and document any necessary changes to mounting, wiring, protection settings, and commissioning procedures.
