Product details

It provides 2 normally open (NO) instantaneous contacts rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, with a surge voltage resistance of 6 kV. The IP20 front protection allows safe panel integration, while the screw and snap-on mounting fits standard DIN rails — the same footprint as the S00 contactor family, so it shares rail space and wiring channels without rework.

The contact ratings are given per voltage level: 10 A at 24 V, 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. These are thermal current ratings for AC loads at the respective voltages — the 10 A at 24 V is the highest current the contacts can carry continuously, while the 6 A at 230 V is the typical rating for a 230 V control circuit. The 6 kV surge voltage resistance means the contactor can withstand transient overvoltages common in industrial panels without flashover, which is critical for reliability in environments with motor switching or nearby lightning paths.

Mechanical endurance and environmental limits

Shock resistance is 10g at 5 ms and 5g at 10 ms, suitable for panel mounting on machinery subject to vibration.

The screw terminals accept solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and 2x 4 mm². The 4 mm² capacity allows daisy-chaining control power through the contactor without an additional terminal block.
