Product details

Motor-protective circuit breaker, 0.16 A, Class 10, 100 kA

It carries a rated continuous current of 0.16 A and is rated for 0.04 kW at 400 V AC-3 duty, meaning it protects a small motor load at that voltage. Breaking capacity is 100 kA at 240 V, 400 V, 500 V, and 690 V AC, so it can safely interrupt fault currents up to that level across common industrial supply voltages without upstream fusing in most panel designs. Phase-failure detection is built in — the breaker trips if one phase drops out, preventing single-phasing damage to the motor. Shock resistance is 25 g for 11 ms.

Terminal and wiring

Main circuit terminals accept screw-type connections: solid conductors 2× (0.5 to 1.5 mm²) and 2× (0.75 to 2.5 mm²); stranded conductors 2× (1 to 2.5 mm²) and 2× (2.5 to 6 mm²). AWG equivalents for main contacts are 2× (14 to 10). Auxiliary and control circuits also use screw-type terminals. The auxiliary switch is transverse design and the product extension supports an auxiliary switch.
