Product details

It provides four normally-open instantaneous contacts rated for 10 A thermal current at 24 V, 6 A at 230 V, and 3 A at 400 V. That 10 A figure governs the continuous current each contact can carry in a control panel; the lower values at higher voltages reflect the switching arc limits for AC loads. The 6 kV surge voltage resistance means it holds off transient spikes common in industrial panels without flashover.

The 45 mm width and 57.5 mm height match the S00 footprint; depth is 111 mm.

Wiring and environmental limits

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, adequate for most machinery applications but not extreme vibration environments. The contact reliability spec — one incorrect switching operation per 100 million cycles at 17 V, 1 mA — indicates the contacts are silver-alloy and suitable for low-level logic signals, not just power switching.

Frequently asked questions

What are the key electrical ratings for this auxiliary contactor?

It has 4 normally-open instantaneous contacts rated at 10 A thermal current at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 500 V. Surge voltage resistance is 6 kV.

What mounting and wiring does this part require?

It mounts on a DIN rail via screw and snap-on, size S00. Accepts solid conductors 0.5 to 4 mm². Operating temperature range is -25 to +60 °C.

What compliance documentation is available for this part?

The evidence records a substance prohibitance date of 07/01/2006, indicating RoHS compliance. The part carries IP20 front protection and 6 kV surge voltage resistance, which are typical for IEC 60947-series conformity, though specific UL/CSA marks are not listed in this evidence.
