Product details

It uses screw-type terminals and carries a maximum rated operational current of 10 A at 24 V, with derated currents at higher voltages — for instance, 6 A at 24 V (AC-15), 3 A at 110 V, and 0.3 A at 220 V. The block is 41.5 mm deep, 28.5 mm wide, and 37.5 mm tall, fitting the compact S00 footprint.

The 1 NO contact is rated for AC-15 duty at 690 V (1 A) and carries a mechanical service life of 10 million switching cycles. The snap-on fastening method integrates directly onto the S00 contactor without additional hardware.
