Product Overview
The GE SSF16G216 is a Power Break II Insulated Case Circuit Breaker used for protection and switching in industrial and commercial electrical distribution systems. It is intended for applications where large electrical loads require controlled interruption and overcurrent protection within a low-voltage distribution system.
As part of a distribution assembly, the circuit breaker monitors current flowing through the protected circuit and interrupts the circuit when a qualifying fault or overcurrent condition is detected. It can also be used for routine circuit switching and equipment isolation during maintenance.
The SSF16G216 is particularly relevant to switchgear, motor control, plant distribution, and other installations where feeder protection must be coordinated with upstream and downstream protective devices.

Product Features
- Power Break II insulated case circuit breaker construction.
- Intended for industrial and commercial power distribution applications.
- Provides circuit interruption during qualifying overcurrent and fault conditions.
- Can serve as a feeder or equipment protection device.
- Supports controlled switching and electrical isolation.
- Suitable for integration into low-voltage switchgear and distribution assemblies.
- Appropriate for plant electrical systems requiring coordinated circuit protection.
Working Principle
The SSF16G216 is installed in series with the circuit being protected. Under normal conditions, current passes through the breaker to supply the connected load.
A simplified protection path is:
Power Source → SSF16G216 Circuit Breaker → Distribution Circuit → Electrical Load
The breaker monitors the electrical conditions of the protected circuit. When an overcurrent or short-circuit condition reaches the applicable trip threshold, the breaker mechanism opens the circuit and interrupts current flow.
Once the circuit has been isolated, maintenance personnel can investigate the fault before restoring power. In normal operation, the breaker can also be operated as a switching and isolation device according to the requirements of the installation.
Role in a Power Distribution Architecture
The SSF16G216 sits between the electrical source and the downstream distribution or load circuit.
| System Element | Function |
|---|---|
| Incoming Power Source | Supplies electrical power to the distribution system |
| Main Distribution Equipment | Routes power to individual feeders |
| SSF16G216 Circuit Breaker | Provides overcurrent protection and circuit interruption |
| Downstream Feeder | Carries protected power to the load or sub-distribution equipment |
| Electrical Load | Consumes the supplied electrical power |
| Protective Coordination System | Coordinates breaker operation with other protective devices |
Correct application requires consideration of the complete distribution system, including available fault current, conductor ratings, downstream equipment, and coordination with other protective devices.
Industrial Applications
| Application | Typical Use |
|---|---|
| Industrial Power Distribution | Feeder and equipment circuit protection |
| Manufacturing Plants | Protection of production equipment power circuits |
| Motor Control Systems | Protection of motor-related distribution circuits |
| Switchgear Assemblies | Main or feeder circuit interruption |
| Commercial Facilities | Protection of building distribution circuits |
| Process Plants | Protection of electrical feeders supplying process equipment |
| Maintenance Power Isolation | Controlled interruption of electrical circuits |
Installation and Maintenance
- Verify the SSF16G216 model and breaker configuration against the electrical system design before installation.
- Confirm that the breaker is suitable for the system voltage, current, fault level, and application.
- Follow the applicable electrical safety procedures and fully isolate the circuit before installation or maintenance.
- Verify that upstream and downstream protective devices are properly coordinated.
- Check busbar, cable, and terminal connections for correct installation and secure contact.
- Inspect the breaker housing and operating mechanism for visible damage before energization.
- Confirm that the breaker operates correctly through its intended manual or control mechanism.
- Check trip and protection functions according to the maintenance procedure specified for the installation.
- Inspect electrical connections periodically for signs of overheating, looseness, or deterioration.
- Investigate the cause of every protective trip before resetting the breaker.
- Keep maintenance records for breaker operation, inspections, testing, and fault events.
- After maintenance, verify correct circuit operation and protective-device status before returning the equipment to service.

Technical FAQs
What is the primary function of the GE SSF16G216?
The SSF16G216 is an insulated case circuit breaker used to protect and switch electrical distribution circuits. Its protection function interrupts the circuit when an applicable overcurrent or fault condition is detected.
Where is the SSF16G216 typically installed?
It can be used in low-voltage distribution equipment such as industrial switchgear, feeder assemblies, motor-related distribution systems, and plant electrical distribution panels.
What should be checked before replacing an SSF16G216?
The breaker configuration, system voltage, continuous current requirements, available fault current, conductor ratings, protection settings, and coordination with upstream and downstream protective devices should be verified before replacement.
What should be investigated after the breaker trips?
Do not simply reset the breaker without identifying the cause. Check the downstream circuit and connected equipment for overloads, short circuits, insulation problems, or other abnormal conditions before restoring power.
