Product details

It mounts directly onto a contactor, saving DIN-rail space and simplifying the wiring run between the contactor output and the motor. Rated for 690 V, with auxiliary contact ratings spanning 24 V (2 A) up to 690 V (0.75 A), so it can switch a PLC input or a contactor coil directly across common control voltages.

RoHS compliance is confirmed with a substance prohibitance date of 10/01/2009, covering the standard EU directive scope.

Integration Notes

Mounts on the contactor via the fastening method, not on a DIN rail — so the panel layout needs the contactor footprint first. The relay body measures 45 mm wide, 87 mm high, and 70 mm deep, fitting into the S00 envelope common across the SIRIUS 3RU2 line. Spring-loaded terminals accept 2x (0.5... 2.5 mm²) solid or stranded wire. A 3 mm screwdriver shaft is specified for the terminal screws.

Frequently asked questions

What does the note 'for message Tripped' mean?

The note indicates that the relay's auxiliary contact is wired to signal a 'Tripped' status — typically to a PLC input or a pilot light — rather than to directly drop out the contactor coil. This is common in remote monitoring setups.

What are the key ratings for this overload relay?

Trip Class 10, rated voltage 690 V, auxiliary contact ratings: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, 0.75 A at 690 V. Size S00, contactor mounting, spring-loaded terminals.
