Working Principle

The breaker operates by continuously monitoring the current flowing through the circuit. In the event of an overload or short circuit, the trip unit activates the mechanism to open the contacts, interrupting the current flow and protecting downstream equipment.

Its arc control system safely dissipates the electrical arc generated during switching, preventing damage to the system.
