Product details

Rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V AC, these contacts handle typical control-circuit loads like PLC inputs, relay coils, and contactor pick-up circuits. The 10 000 000 mechanical operating cycles mean it outlasts most panel revisions.

Screw terminals accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x 4 mm², so no special ferrules needed. Depth: 117 mm.

Pollution degree 3 (industrial environment). RoHS compliance date of October 1, 2009 — the part meets the EU directive. Relative humidity minimum 10%.
