Product details

Auxiliary contactor for control-circuit switching

It carries 2 normally-open and 2 normally-closed instantaneous contacts, with a thermal current rating of 10 A at 24 V and 6 A at 230 V. The 6 kV rated surge voltage resistance gives it margin for industrial control panels where transient suppression is already present on the coil side.

Screw and snap-on mounting means it clips onto the rail without tools and can be screw-fastened for vibration-prone installations. The terminal block accepts solid conductors: two wires of 0.5 to 1.5 mm², two of 0.75 to 2.5 mm², or a single 4 mm² per clamp. IP20 on the front face protects against finger contact inside an enclosed panel.

Shock resistance is 10g for 5 ms and 5g for 10 ms. The substance prohibition date of July 1, 2006 aligns with RoHS compliance.
