It carries four normally-open main contacts rated 10 A in AC-12 (control-circuit duty), so it can also serve as a high-current interposing relay in PLC output circuits. The 24 VDC coil draws 3.3 W both on pickup and hold, which simplifies the DC supply budget — no inrush spike to size for. The main contacts are screw-type terminals accepting 2x 0.75 to 4 mm² solid or stranded, or 2x 20 to 14 AWG, with a single 12 AWG also allowed. The auxiliary contact ratings cover 10 A at 24 V down to 0.3 A at 220 V DC, which covers most DC control circuits in industrial panels. At 72 mm deep, 57.5 mm tall, and 45 mm wide, the S00 frame fits standard 45 mm pitch DIN-rail layouts. The screw terminals are accessible from the front, so wiring in a dense row is straightforward. The coil holding power is the same as the closing power — 3.3 W DC — which means no additional heat sink or derating for continuous energization. For a 24 VDC supply, that is about 137 mA continuous draw per contactor.","metaTitle":"Siemens 3RT1316-1BG40 SIRIUS Power Contactor, S00, 4NO, 10 A","metaDescription":"Siemens 3RT1316-1BG40 SIRIUS power contactor, size S00, 4 NO main contacts, 10 A AC-12 rated, 4 kW at AC-2 400 V.
