Product details

Rated for 690 V, the relay handles line voltages up to that level. The auxiliary contact block is integrated and rated for switching: 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 contact ratings for the trip-indication and alarm circuits, not the main power path. The relay carries a note: "for message 'Tripped'" — this is the auxiliary contact that changes state when the overload trips, providing a signal back to a PLC or indicator lamp.

Mounts directly onto a contactor (contactor mounting) in any position. Dimensions: 45 mm wide, 76 mm high, 70 mm deep — fits standard S00 contactor footprints. Main circuit terminals are screw-type, accepting 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded wire. The screwdriver shaft should be 5…6 mm diameter with a Pozidriv PZ 2 tip. Temperature compensation is active from -40 to +60 °C, keeping the trip curve accurate across that ambient range.

Substance compliance: the relay meets the substance prohibitance date of 10/01/2009, indicating RoHS compliance for materials restricted as of that date.

Frequently asked questions

What is the note "for message 'Tripped'" on this relay?

It refers to the auxiliary contact that signals when the overload relay has tripped, used for remote indication or PLC input.

What compliance documentation is available for this relay?

The relay meets the substance prohibitance date of 10/01/2009, consistent with RoHS compliance for that cutoff.
