This saves a panel builder a component and the wiring between a separate breaker and overload relay. Breaking capacity sits at 100 kA at 400 V and 240 V, dropping to 42 kA at 500 V and 4 kA at 690 V.
Any mounting position is allowed, which simplifies layout in crowded enclosures. Dimensions are 97 mm deep, 65 mm wide, and 97 mm high. Clearance requirements: 50 mm above and below, 30 mm to the side, zero front and back. Main circuit terminals accept 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire, terminated with M3 screws. This covers standard motor connection cables up to 2.5 mm².
