Siemens 5ST3062 Auxiliary Switch 1 Changeover Contact 0.5 Module Width AC 230/400V DC 24-220V

In modular electrical installations, auxiliary switches are needed to signal the status of circuit breakers or residual current devices. The Siemens 5ST3062 provides a reliable changeover contact in a compact 0.5 module width, enabling status indication and control functions in SENTRON distribution boards.

Who is it for

Electricians and panel builders who install Siemens SENTRON modular devices and need a space-saving auxiliary switch for signaling or interlocking.
