It combines a contactor and thermal overload relay in one unit, covering motor power from 0 to 6 kW across 100–690 V three-phase supplies. The adjustable thermal overload class spans 5 to 30, and the tripping threshold is fixed at 1.25× In per IEC 60947-4-1.
The motor power range is given per voltage band — for example, 0–0.5 kW at 100–120 V, up to 4–6 kW at 380–690 V. That means the same unit covers a wide range of small-to-medium motor loads, but the actual kW limit depends on your line voltage. The thermal overload class adjustment (5–30) lets you match the trip curve to the motor's thermal time constant — class 10 for standard motors, class 20 or 30 for high-inertia loads like fans or crushers.
Mounts under a contactor plate or on a rail with specific accessories. Dimensions: 3.1 in deep, 1.8 in wide, 2.9 in tall. Power circuit terminals accept up to 16 mm² solid or flexible wire; control circuit terminals accept 2.5 mm². Tightening torque is 3.1 N·m on the power side, 0.8 N·m on the control side.
