SIRIUS auxiliary contactor for signal switching and control logic
Its 2 NO instantaneous contacts handle rated operational currents from 10 A at 24 V and 230 V AC down to 0.26 A at 600 V AC, covering the voltage range typical of 24 VDC control buses and 230/400 VAC line-level signaling. The DC coil draws 4 W on pick-up and 4 W holding, a steady-state load that a 24 VDC power supply or PLC output card must budget for per contactor.
The switching capacity table tells the real story: at 24 V rated value the contacts carry 10 A, at 230 V rated value also 10 A, but at 440 V rated value that drops to 0.5 A and at 600 V rated value to 0.26 A. This derating follows the arc-quenching limits of the S00 air gap — for a 480 V control circuit, verify the load current against the 440 V column. The mechanical life of 30,000,000 cycles is the theoretical limit; electrical life will be lower and depends on the switched load, but the figure confirms the contactor is rated for high-cycle applications like pick-and-place or packaging lines.
The S00 footprint — 45 mm wide, 57.5 mm tall, 73 mm deep — fits standard 45 mm slot spacing. Terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded copper. The product extension auxiliary switch is available, meaning additional contact blocks can be ganged onto this base unit without replacing the coil assembly.
