It mounts directly to a contactor and uses bimetallic strips to model motor heating, tripping the contactor via an integrated auxiliary switch when the thermal model exceeds the set point. Auxiliary contacts carry 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 — enough to signal a PLC input or drop out a contactor coil.
Fastens directly to the contactor — no DIN rail or panel drilling needed. The relay occupies the S00 footprint: 45 mm wide, 76 mm tall, 70 mm deep. Main circuit terminals accept screw-type connections: 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded. The screwdriver tip required is Pozidriv PZ2, shaft diameter 5–6 mm. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate even near a hot motor or in a cold warehouse.
What the note means
The part carries a note: "for message 'Tripped'". That means the integrated auxiliary switch is wired to signal a "tripped" status — typically a normally-closed contact that opens when the relay trips, feeding a PLC digital input or a panel indicator. No external add-on module is needed for basic trip indication.
