The relay mounts directly onto a contactor via the M8 main contact fastening method, eliminating separate panel wiring for the power circuit.
Rated insulation voltage is 690 V, with a rated operating voltage up to 1 000 V in AC-3e duty — this covers 690 V motor circuits common in European and North American industrial panels. Power dissipation per pole is 4.5 W; at full load on a three-phase motor, expect roughly 13.5 W total heat inside the enclosure — factor this into your panel thermal budget. The auxiliary contact ratings are given across multiple 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 are the switching limits for the trip-indication circuit, not the main motor current.
The relay accepts screw-type terminals for the main circuit: solid conductors 2× (2.5 to 16 mm²), stranded 2× (6 to 16 mm²), and larger cables up to 1× (10 to 70 mm²) stranded for the line side. Control-circuit wiring uses a separate terminal pair accepting 2× (0.5 to 2.5 mm²) solid or stranded — keep these wires segregated from the power conductors to avoid induced noise on the trip signal.
Substance prohibitance compliance date is March 1, 2017, indicating the design meets RoHS and REACH substance restrictions as of that revision.
