This one is sized for the S00 frame contactor family, so it bolts directly onto the bottom of a matching S00 contactor without extra brackets or wiring between them. For a pump, fan, or light conveyor, this is the right call. The thermal bimetal release is temperature-compensated from -40 °C to +60 °C, so it won't nuisance-trip on a hot day or fail to protect in a cold plant. The built-in auxiliary contact (integrated, no add-on needed) is rated across a wide voltage range: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V — that covers the trip-signal circuit whether you're feeding a 24 VDC PLC input or a 230 VAC alarm light.
Mounting and wiring in the panel
Mounts directly to the contactor. Spring-loaded terminals on the main circuit accept 2x 0.5 to 2.5 mm² solid or stranded. A 3 mm diameter screwdriver tip is used for auxiliary terminal screws.
Substance prohibitance date of October 1, 2009 aligns with the original EU RoHS deadline — so this part has been RoHS-compliant for over a decade. No REACH or UL marking is explicitly in the evidence, but the SIRIUS line typically carries IEC/EN 60947-4-1 certification.
