Product Overview
The GE TEDAS2AB2 Auxiliary Switch is an electrical accessory associated with compatible GE circuit breaker equipment. Auxiliary switches are used in low-voltage switching and control arrangements to provide an electrical indication of a circuit breaker’s operating position. This status information can be used by external control circuits, monitoring equipment, annunciation systems, and other devices that need to determine whether the associated breaker is open or closed.
In industrial electrical distribution systems, circuit breakers do more than interrupt current during abnormal conditions. Their operating status may also need to be communicated to a control panel, motor control circuit, building management system, or supervisory monitoring platform. An auxiliary switch provides a contact state that changes according to the associated breaker’s mechanical position, allowing external circuits to respond to the breaker status without relying solely on direct observation.
The TEDAS2AB2 is relevant to installations where a compatible breaker requires auxiliary contact functionality for status indication or control-circuit integration. During equipment selection, technicians should confirm the exact breaker family, accessory mounting arrangement, contact configuration, and electrical ratings specified by GE documentation. Auxiliary switches are not universally interchangeable, even when they appear similar or share a general accessory category.
For maintenance and replacement work, identifying the complete TEDAS2AB2 model number helps ensure that the selected accessory matches the existing breaker and the intended control-circuit application. Correct installation and wiring are important because an incorrectly configured auxiliary contact can cause inaccurate status indication, prevent a monitoring circuit from receiving the expected signal, or affect the operation of equipment that depends on breaker-position feedback.

Product Features
- Breaker status indication: The TEDAS2AB2 is an auxiliary switch intended to provide an electrical indication associated with the operating position of compatible circuit breaker equipment. Its contact state can be used by an external circuit to determine whether the breaker has reached the relevant mechanical position.
- Integration with control circuits: Auxiliary contacts allow breaker status to be incorporated into electrical control schemes. Depending on the system design, the contact signal may be routed to a control panel, monitoring input, annunciator, or another circuit that requires breaker-position information.
- Mechanically associated switching: An auxiliary switch generally follows the movement of the associated breaker mechanism. This arrangement allows the external contact state to reflect the relevant breaker position without requiring a separate sensor to observe the breaker manually.
- Support for remote status monitoring: Where the breaker and control system are configured for remote monitoring, auxiliary contact information can be used to report breaker position to an operator interface or supervisory system. The exact indication available depends on the contact configuration and the connected circuit.
- Model-specific accessory identification: The TEDAS2AB2 designation provides a reference for identifying the intended switch accessory during procurement, installation, and maintenance. Checking the full model number helps prevent confusion with other auxiliary switches or breaker accessories.
- Electrical panel integration: An auxiliary switch can form part of a broader panel wiring arrangement that combines circuit protection, interlocking, status feedback, and operator indication. Its installation must follow the specified breaker accessory arrangement and applicable wiring requirements.
- Support for maintenance replacement: If an existing auxiliary switch becomes damaged or no longer provides the expected contact operation, a correctly matched replacement can help restore the required status feedback. Compatibility must be established before installation.
- Contact-based signal interface: The auxiliary switch provides a contact interface for external electrical circuits. The connected circuit must be designed for the contact configuration and ratings documented for the particular model.
- Improved equipment status visibility: When correctly installed and wired, auxiliary contacts help make breaker operating status available to control and monitoring equipment, reducing dependence on local visual inspection alone.
- Application-specific selection: Auxiliary switches may differ in mounting methods, contact arrangements, electrical ratings, and operating behavior. The TEDAS2AB2 should be selected according to the associated breaker and the requirements of the intended control circuit.
Working Principle
The GE TEDAS2AB2 operates as an auxiliary contact device associated with a compatible circuit breaker. When the breaker mechanism changes position, the associated mechanical movement actuates the auxiliary-switch mechanism. This movement changes the state of the switch contacts according to the contact arrangement provided by the specific accessory.
The contact state can then be used by an external circuit as a representation of the breaker position. For example, a monitoring circuit may use an auxiliary contact to indicate that a breaker has opened, while another control circuit may use a contact state as a permissive condition before allowing a subsequent operation. The actual logic depends on the circuit design and whether the selected contact is configured as normally open, normally closed, or another documented arrangement.
In a typical status-monitoring application, the auxiliary contact is wired to a compatible input on a control panel or monitoring device. When the breaker changes position, the contact changes state and the connected circuit detects the resulting electrical condition. The control system can then display the status, activate an indication, record an event, or evaluate the signal as part of an interlocking sequence.
The auxiliary switch does not replace the breaker’s primary protective mechanism. The circuit breaker remains responsible for switching and interrupting the power circuit within its specified operating capabilities. The auxiliary switch supplies a separate status contact for external electrical use; it should not be assumed to measure load current, detect faults independently, or provide a protective trip function unless the relevant documentation explicitly states otherwise.
During commissioning and troubleshooting, technicians should verify the accessory mounting, mechanical actuation, contact continuity, terminal identification, and external wiring. If the indicated status does not correspond to the breaker position, the investigation should include the switch mechanism, contact configuration, connected wiring, and receiving control input.
