Siemens 5SH5404 spúšťacia cievka 24V AC/DC pre príslušenstvo MCB

Shunt trip accessory for Siemens miniature circuit breakers, enabling remote tripping of 5SY, 5SP, and 5SL series MCBs. This side-mounted module operates at 24 V AC or DC, providing a reliable method to disconnect circuits from a distance for safety or control purposes. With a compact 1-module width, it integrates seamlessly into distribution boards without sacrificing space.

Advantages

The shunt trip allows for immediate circuit interruption upon receiving an external signal, enhancing system safety and enabling automated shutdown in emergency situations. Its screw terminals accept solid or stranded conductors from 0.75 to 2.5 mm², ensuring secure and straightforward wiring. The device is built to withstand harsh conditions, with an operating temperature range from -25 to +55 °C and storage from -40 to +75 °C. Compliance with IEC/EN 60947-2 guarantees high quality and reliability.
