The coil operates on a 21-28 V supply with an inrush peak of 3 A.
Switching duty and operating rates
Rated for up to 1 000 switching operations per hour under AC-1, AC-2, and AC-3 duty. Under AC-4 (frequent starting, plugging, or reversing of motors) the rate drops to 300 1/h. This matters when sizing for heavy inductive loads — you cannot cycle an AC-4 application at the same speed as a standard motor start.
Mechanical and environmental
Dimensions: 85 mm high, 45 mm wide, 107 mm deep. The S0 frame footprint is shared across the SIRIUS contactor range, so auxiliaries and accessories for this frame size are a known panel cutout. Operating temp from -25 to +60 °C; store at -55 to +80 °C.
