Its 3 NO + 1 NC pole configuration covers most interlocking and signalling needs on a motor starter or feeder. The 24 V AC 50 Hz coil matches standard control transformer secondaries common across European and Asian installs. Rated operational voltage up to 690 V, with utilisation categories AC-14 and AC-15 — meaning it is tested for switching electromagnetic loads like contactor coils, solenoid valves, and small motor starters, not resistive loads.
At 45 mm wide and 74 mm tall, this relay occupies a single 45 mm DIN-rail pitch — standard for a four-pole control relay in the Easy TeSys family. Depth of 80 mm leaves clearance behind a 120 mm deep enclosure. IP2X means finger-safe terminals; no special cover needed in a closed panel. The 3000 m altitude rating without derating covers most installations outside high-mountain sites.
This covers acceptance in most IEC-market jurisdictions. The mechanical robustness specs — 7 Gn shock open, 10 Gn closed, vibration 1.5–3 Gn across 5–300 Hz — confirm it survives the typical panel door slam and nearby contactor chatter.
