Product details

DIN-rail auxiliary contactor, Size S00

It carries a 10 A rated value at 24 V, making it a fit for control-circuit switching in panels where space is tight — the S00 footprint keeps the DIN-rail fill factor low.

Dimensions are 57.5 mm high, 45 mm wide, 73 mm deep.

Contact ratings and switching capacity

Rated at 10 A at 24 V and 230 V, with derated values at higher voltages: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V, and 1 A at 690 V. Switching frequency at DC is 10,000 operations per hour. The contactor has 2 instantaneous contacts.
