At 24 VDC the contactor switches 10 A; at 110 VDC it switches 1 A; at 220 VDC it switches 0.3 A. Those DC ratings are the ones to check if you're breaking DC loads — the arc extinction is different from AC, and these numbers are the limit. The coil holds at 110 VDC nominal, with a pick-up threshold of 0.85 x rated voltage and a drop-out of 1.1 x rated voltage. Closing power is 3.3 W DC; holding power is the same 3.3 W — a DC coil that doesn't reduce power after pull-in, so the coil stays warm. Verify your control transformer can supply the inrush without sagging below 93.5 VDC. That's typical for industrial control panels not in a sealed, climate-controlled room. For type 1 coordination (device may be damaged but no fire risk), it's gL/gG 35 A. Wire the main circuit with screw terminals accepting 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) solid, or up to 2x (0.75 to 4 mm²) stranded with ferrules.","metaTitle":"Siemens 3RT1316-1BF40 SIRIUS Power Contactor, 4 NO, 110 VDC","metaDescription":"Siemens 3RT1316-1BF40 SIRIUS power contactor, Size S00, 4 NO main contacts, 110 VDC coil, 4 kW at AC-2 400 V.
