The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded conductors, or 2x (0.25 to 1.5 mm²) finely stranded with ferrule — no screw torque to verify, which speeds panel wiring. The S00 footprint (45 mm wide, 60 mm tall, 72 mm deep) packs into tight sub-panel layouts. The DC magnet coil draws 3.3 W holding power — continuous-duty rated, no economizer resistor needed. Coil operating range is 0.85 to 1.1 x rated voltage (230 V coil version). Operating ambient -25 to +60 °C, with altitude derating above 2000 m. Mechanical life rated at 30 million operating cycles typical.","metaTitle":"Siemens 3RT1316-2BP40 SIRIUS S00 Power Contactor, 4 NO, 4 kW","metaDescription":"Siemens SIRIUS 3RT1316-2BP40 power contactor, size S00, 4 NO main contacts, 4 kW AC-2 at 400 V, spring-loaded terminals, IP20, DIN-rail mount.
