It combines a circuit breaker and overload relay in one unit, with Trip Class 10 protection. It also includes phase failure detection, so if one leg drops out, the breaker opens before the motor single-phases and cooks the winding.
Mounting and terminals
Any mounting position is allowed, which gives flexibility in tight cabinets. The main circuit uses spring-loaded terminals — no screwdriver needed for the power wires, just strip and push. Accepts 2 x 0.5 to 2.5 mm² solid or stranded. That 45 mm width is a single module on the rail — leaves room for other breakers or contactors in the row.
Environmental and aux ratings
Storage and transport range extends from -50 to +80 °C. Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, 0.15 A at 60 V. Rated operational voltage spans 20 to 690 V AC.
