Product details

It carries a maximum thermal current of 3 A, with specific switching capacities of 1 A at 24 V DC, 0.2 A at 125 V DC, and 0.1 A at 250 V DC — these ratings define the load it can break in a control circuit, not a power circuit. The switch offers an adjustable time delay from 0.05 to 1 s, with a recovery time of 150 ms, and a minimum ON period of 200 ms, making it suitable for sequenced or delayed signaling in a panel.

Its dimensions — 45 mm wide, 38 mm high, 75 mm deep — mean it adds minimal footprint to the existing contactor assembly. It accepts solid or stranded wire from 18 to 14 AWG, with dual terminals for 2x (20...14) AWG solid, simplifying daisy-chain wiring in a panel.
