It is rated for a 24 VAC coil at both 50 Hz and 60 Hz, and carries a 10 A rated operational current at AC-12 (resistive load).
The S00 frame size (45 mm wide, 57.5 mm tall, 72 mm deep) is the smallest SIRIUS contactor footprint, so it fits in tight panel spaces where a larger frame would not. The 10 A AC-12 rating means it can switch resistive heater or lighting loads up to that current continuously — but for motor duty, use the AC-3 or AC-4 ratings. At AC-4 (frequent inching/plugging) at 400 V, it is rated 6.5 A, which governs the motor size for reversing or jogging applications. The coil holds at 24 VAC nominal; the operating range is 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz, so a sag below ~19 VAC at 50 Hz drops it out. This matters when coordinating with upstream breakers in a motor control center. The screw-type terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded wire — standard for panel wiring up to 4 mm². Maximum operating altitude is 2000 m without derating.
