What this auxiliary contactor is and where it fits
The Siemens SIRIUS 3RH1362-1UB40-0KV0 is an auxiliary contactor in size S00, designed for switching control and signaling circuits in industrial panels. It carries 6 normally-open instantaneous contacts and 0 normally-closed — a pure make-side block for applications that need multiple NO signal paths without a break contact. The coil is rated 24 V DC, with a closing and holding power of 3.2 W each, so the power supply budget is predictable: 3.2 W steady-state draw per contactor.
What the ratings mean for the buyer
The 10 A rated current at 24 V tells you the contact set can handle the inrush and sealed current of multiple small relays or PLC inputs downstream — useful for splitting a single signal into several branches. The switching capacity drops with voltage: at 110 V it's 1 A, at 230 V it's 6 A, at 400 V it's 3 A, at 690 V it's 1 A (–). That's a standard derating curve for an auxiliary contactor; pick the voltage column that matches your control voltage. The IP20 front protection means the contactor is safe from finger contact but not sealed against dust or moisture — it belongs inside a closed panel, not in a washdown zone.
Mounting and integration into the panel
This contactor mounts by screw or snap-on onto a DIN rail. At 45 mm wide, it takes up one standard 45 mm module slot. The mounting position is flexible: it can be rotated ±180° on a vertical surface and tilted forward/backward ±22.5° — useful when you're fitting into a crowded gland-plate area or need to orient the terminals for wire routing. The screw terminals accept solid conductors from 0.5 mm² up to 4 mm², which covers the typical control-wire gauges in a panel.
