Overview
The Siemens 5ST3010 Auxiliary Switch is a crucial accessory designed to integrate seamlessly with a wide range of Siemens SENTRON protection devices. This compact, high-performance switch provides vital remote status indication for your miniature circuit breakers (MCBs), residual current operated circuit breakers (RCBOs), and residual current circuit breakers (RCCBs). Featuring a 1 NO (Normally Open) and 1 NC (Normally Closed) contact configuration, the 5ST3010 allows electrical control systems, PLCs, or remote monitoring panels to accurately track the operational status (ON/OFF/Tripped) of the primary protective device. It is an indispensable component for safety-critical industrial, commercial, and residential automation systems.
