Product details

It mounts directly to a contactor and provides an integrated auxiliary switch with a range of contact ratings: 24 V 2 A, 60 V 0.3 A, 110 V 0.22 A, 120 V 3 A, 125 V 0.22 A, 230 V 2 A, 400 V 1 A, and 690 V 0.75 A.

Mounting is via contactor fastening (M3 screws for main contacts), and the relay can be installed in any position. The screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire, and the screwdriver tip is Pozidriv PZ 2 with a 5-6 mm shaft diameter. The integrated auxiliary switch eliminates the need for a separate add-on block.
