Product details

Motor protection circuit breaker for panel integration

Breaking capacity and voltage ratings

This breaker delivers 100 kA breaking capacity at 240 V and 400 V AC, dropping to 42 kA at 500 V and 4 kA at 690 V. At 480 V and 600 V the rated current is 8 A. These ratings cover most industrial motor branch circuits in North American and European voltage systems.

Clearance requirements: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards. Screw-type terminals for the main current circuit accept solid or stranded conductors: 2x (1…2.5 mm²) and 2x (2.5…10 mm²).
