3VA9477-0GX20 SIEMENS

The 3VA9477-0GX20 auxiliary switch module from Siemens is designed to enhance the functionality of your 3VA series molded case circuit breakers (MCCBs). This module provides crucial signaling capabilities, indicating the operational status of the circuit breaker. Specifically, it features two leading contacts that signal when the breaker is switched to the "ON" position. Additionally, it includes one leading contact that signals when the breaker is switched to the "OFF" position. This auxiliary switch module is compatible with 3VA5 250/400/600 and 3VA6 150/250/400/600 frame size circuit breakers. It is easily integrated into the circuit breaker's operating mechanism, providing reliable and accurate status indication. The auxiliary switch is essential for remote monitoring and control applications, enabling operators to quickly assess the state of the circuit breaker from a central location. This module is particularly useful in automated systems where real-time feedback on circuit breaker status is critical for efficient operation and safety. By providing clear and timely signals, the 3VA9477-0GX20 auxiliary switch module contributes to improved system reliability and reduced downtime.
