Siemens 5TE5802 Auxiliary Switch, 1NO+1NC, Side Mount, Multicolor

Monitoring and signaling in modular installations often requires an extra contact that reacts exactly when the main protective device trips. The Siemens 5TE5802 auxiliary switch solves this by providing a reliable changeover contact that mounts directly onto compatible SENTRON miniature circuit breakers, residual current devices, and RCBOs. It turns a simple breaker into a status-reporting component, enabling remote indication or control without complex wiring.

Who is it for

Panel builders, electricians, and maintenance technicians who need to integrate status feedback from Siemens SENTRON protection devices into building management systems, PLCs, or indicator lamps. Ideal for distribution boards where space is limited and side-mounted accessories are preferred.

Tips

Verify compatibility with your specific SENTRON device model before ordering. The auxiliary switch clips onto the side without tools, but ensure the main device is de-energized during installation. For higher switching loads, consider an additional contactor.
