Product details

It's built for switching resistive and lightly inductive loads in control circuits, not as a main power contactor for motor starting — the S00 frame and 24V coil place it in the signal-level coupling role, typically interposing between a PLC output and a larger contactor or motor starter. The 45 mm width and 70 mm height with 73 mm depth fit the S00 footprint — standard for DIN-rail panels where space is allocated per contactor size.

Switching Capability and Duty Cycles

The 24 V DC coil picks up at 0.7x rated and drops out at 1.25x rated, with a DC switching time of 7 to 20 ms and arcing time of 10 to 15 ms. That arcing window matters for DC circuits — the contact gap must clear the arc before the next switching event, and at 24 V rated value it handles 10 A. At higher voltages the current rating drops: 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The 230 V rating is expressed as 0.75 hp, which is the standard motor horsepower equivalent for that voltage. Maximum operating frequency varies by duty: 1,000 cycles/hour at AC-1, 750 cycles/hour at AC-2, AC-3, and AC-3e, and 250 cycles/hour at AC-4. The AC-4 limit is the binding one for frequent plugging or inching duty — if your application requires more than 250 cycles/hour under AC-4, this contactor will exceed its thermal limit.
