SIRIUS S10 contactor — 265 A AC-3, 2 NO + 2 NC aux
The 3RT1363-6AR36 is a Siemens SIRIUS contactor in size S10, rated for motor switching at 265 A in AC-3 duty (cites:,). That puts it squarely in the heavy motor-starter class — think large pumps, compressors, or conveyor drives drawing over 130 kW at 400 V. The coil accepts 250–500 VAC 50/60 Hz (cites:,). Pick-up voltage is 0.8× rated; drop-out is 1.1× rated (cites:,). At 400 V that means the coil pulls in reliably at 320 V and drops out at 440 V — useful headroom for brownout-prone sites. Built-in auxiliary contacts: 2 NO + 2 NC, with ratings from 3 A at 24 V up to 4 A at 230 V and 2 A at 690 V (cites:,). These handle feedback to a PLC or status indication without an add-on block.
Panel fit and operating range
Dimensions: 153 mm deep, 140 mm wide, 196 mm high (cites:,). Mounts on a vertical surface via screw fixing, and can be rotated ±180° or tilted forward/backward up to 30° when at 0° rotation (cites:,). That flexibility matters when retrofitting into existing panels with odd clearances. The wide cold-end range makes it viable for unheated enclosures in northern climates or freezer applications. Solid/stranded wire capacity: 1x (1–4 mm²) or 2x (1–4 mm²) per terminal (cites:,). Screw-type coil terminals (cites:).
