Siemens MCB is useful as it protects systems and installations in buildings and for industrial applications. Also, used in industrial applications and plant engineering, we can supplement miniature circuit breakers with additional components. Such as auxiliary switches, fault signal contacts, shunt trips, under-voltage releases, remote controlled mechanism, RC units, and arc fault detection devices.
Similarly, according to IEC standards for power supply systems up to 250/440 V AC. 72 V DC per pole permit in DC systems.
The 5SY miniature circuit breakers are ideal for the quick and easy mounting of auxiliary switches and fault signal contacts. Captive metal brackets on the additional components ensure the quick and easy mounting of devices on the miniature circuit breakers without the need for tools.
