Three-phase circuit breakers

Discover our selection of three-phase modular circuit breakers designed for electrical panels with a 400V power supply. Mounted on a DIN rail, they protect circuits against overloads and short circuits, with coordinated phase shutdown depending on the model selected. Their use is recommended to protect three-phase circuits that power motors, pumps, workshop machinery, heating systems, terminals, or power circuits. Depending on your installation, choose a 3-pole or 4-pole circuit breaker with a rating appropriate for the circuit's current and a trip curve consistent with the type of load.
