3RV2901-1B SIEMENS

The 3RV2901-1B auxiliary switch from Siemens is designed for side mounting on 3RV2 circuit breakers, enhancing their functionality with additional signaling capabilities. This auxiliary switch features two normally open (2 NO) contacts, providing reliable indication of the circuit breaker's status. Its primary function is to signal the operational state of the circuit breaker, such as whether it is open, closed, or tripped. The screw terminal connections ensure a secure and robust electrical connection, minimizing the risk of loose wiring and ensuring consistent performance. This auxiliary switch is particularly useful in applications where remote monitoring or control of the circuit breaker is required. It allows for easy integration into control circuits and automation systems, providing real-time feedback on the circuit breaker's condition. By adding this auxiliary switch, users can improve the overall safety and efficiency of their electrical systems, enabling quick response to any changes in the circuit breaker's status. The compact design of the 3RV2901-1B ensures that it does not significantly increase the overall size of the circuit breaker assembly. It is an essential component for comprehensive circuit protection and management.
