Product details

It carries 3 normally-open and 1 normally-closed instantaneous contacts, rated at 10 A at 24 V, with a 24 VDC coil that pulls and holds at 3.2 W.

For inductive loads like small relays or solenoid valves, derate per the switching curves: at 110 V it's rated 1 A, at 220 V it drops to 0.27 A. The 6 kV rated surge voltage means the contactor can withstand transient overvoltages common on industrial 24 VDC control buses without flashover. Shock resistance of 10g at 5 ms and 5g at 10 ms covers most vibration environments on a machine base or panel door — no special dampening needed for standard conveyor or pump skids.

Depth is 114 mm, height 60 mm. Screw terminals accept 2x 0.25 to 2.5 mm² solid or stranded wire (2x 24 to 14 AWG). The holding power stays at 3.2 W DC, so the coil doesn't heat the enclosure noticeably even in a sealed panel.
