Product details

The instantaneous short-circuit trip responds at 585 A, a magnetic-only release that clears faults fast enough to protect downstream contactor and cable in a starter combination. Insulation voltage rated 690 V with pollution degree 3 at AC.

The S2 frame (55 mm wide, 149 mm deep, 140 mm tall) fits standard panel layouts. Clearance requirements: 50 mm above and below, 140 mm forward, 30 mm to the side — plan your enclosure depth and busbar spacing accordingly. Terminals accept 2x 0.75–25 mm² or 1x 0.75–35 mm² solid/stranded, with screw torque 3–4.5 N·m. Top and bottom entry for main circuit wiring.

RoHS compliance date marked July 1, 2006 — the part meets the original EU RoHS directive. No REACH or UL listing in the evidence, but the SIRIUS series typically carries IEC/EN 60947 certifications.

3 poles, 50/60 Hz, 20 W typical power loss. Operating temperature -20 to +60 °C, storage -50 to +80 °C. Shock rated 25g / 11 ms per IEC 60068-2-27. Maximum operating altitude 2,000 m. Maximum switching frequency at AC-3 duty is 15 operations per hour — adequate for typical motor starting cycles, not for high-speed jogging. Surge voltage resistance 6 kV, relative humidity 10–95 % during operation.
