It mounts directly to a contactor and provides motor protection by monitoring current and tripping on overload. The integrated auxiliary switch signals a tripped condition — the part carries a "for message 'Tripped'" note, meaning the auxiliary contacts change state when the relay operates.
The relay is rated for motor loads at several voltages: 7.5 kW at 400 V, 11 kW at 500 V, and 15 kW at 690 V. At 480 V and 600 V the continuous current rating is 20 A. The auxiliary contacts are rated for switching at common control voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. These ratings define the maximum load the relay can protect and the signal it can pass back to a PLC or indicator.
Fastening method is contactor mounting — it clips directly onto the matching contactor without extra hardware. The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. For the main contacts, a Pozidriv PZ 2 tip with a shaft diameter of 5 to 6 mm is specified. Dimensions: 55 mm wide, 90 mm high, 105 mm deep. Mounting position is any, and temperature compensation is active from -40 to +60 °C.
