Miniature circuit breakers are used to protect systems and installations in buildings and for industrial applications. Used in industrial applications and plant engineering, miniature circuit breakers can be supplemented with additional components, such as auxiliary switches, fault signal contacts, shunt trips, undervoltage releases, remote controlled mechanism, RC units, and arc fault detection devices. The devices are approved for worldwide use according to IEC standards for power supply systems up to 250/440 VAC. 72 VDC per pole is permitted in DC systems.

SUPPLEMENTARY PROTECTION
Type B characteristic designed for European residential circuit protection. This characteristic can also be used for protection of computers and electronic equipment. Magnetic trip point - 3 to 5 times In rating. Thermal trip point - 1.13 to 1.45 protecto
Clear and visible conductor connection in front of the rear busbar facilitates controls
The conductor is easily inserted into the terminal thanks to the large and easily accessible wiring space
Double terminal chambers permit accommodation of two wires of different cross-sections
Quick and easy manual removal of miniature circuit breakers from the busbar assembly, for example if connections need to be changed
Time-saving replacement of parts as busbars no longer need to be freed from adjacent devices
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
Class B trip
