Breaking capacity and fault clearing
This breaker clears 100 kA at 240 V AC, 50 kA at 400 V AC, 3 kA at 500 V AC, and 2 kA at 690 V AC. The surge voltage resistance rating of 6 000 V ensures the internal gap withstands switching transients on inductive motor circuits.
The 45 mm width and 90 mm height fit standard motor starter assemblies in a control panel. Terminal capacity accepts 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²) — sized for the motor leads this breaker typically protects.
