3RV2901-1E SIEMENS

The 3RV2901-1E auxiliary switch from Siemens is designed to seamlessly integrate with 3RV2 circuit breakers, enhancing their functionality with added control and monitoring capabilities. This transverse-mounted auxiliary switch features a combination of one normally open (NO) and one normally closed (NC) contact, providing versatile signaling options for various applications. Its primary function is to indicate the operational status of the circuit breaker, such as whether it is open, closed, or has tripped due to an overload or short circuit. The screw terminal connections ensure a secure and reliable electrical connection, minimizing the risk of loose wiring and ensuring consistent performance. This auxiliary switch is particularly useful in automation systems, motor control centers, and other industrial applications where remote monitoring and control of circuit breakers are essential. By providing real-time status updates, the 3RV2901-1E enables prompt response to any abnormal conditions, improving system reliability and reducing downtime. Its compact design allows for easy installation alongside the circuit breaker without significantly increasing the overall footprint. Furthermore, the robust construction of the switch ensures durability and long-term performance in demanding industrial environments. This auxiliary switch is an indispensable component for comprehensive circuit protection and control.
