Product details

It carries six instantaneous contacts — four normally open and two normally closed — with a rated 24 VDC coil that draws 4 W during both closing and holding, so the coil power supply sees a steady load with no inrush surge.

The contactor is rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, among other voltage-specific ratings — meaning the same contact set handles both low-voltage DC pilot circuits and higher-voltage AC control loads, but the ampacity drops as voltage rises. The switching frequency reaches 10,000 operations per hour (AC), with an arcing time of 10 to 15 ms and a DC switching delay of 7 to 13 ms, which matters when coordinating with PLC scan cycles or safety relay timing.

Frequently asked questions

Will 3RH2262-1BB40 drop into a panel that was specified around 3RH2131-1AH00 without rewiring?

No — the 3RH2262-1BB40 is size S00 (45 mm wide, 57.5 mm high, 117 mm deep) while the 3RH2131-1AH00 is a different size class. The mounting hole pattern, DIN-rail clip position, and terminal layout may differ. Always compare the dimensional drawing and terminal assignment before assuming interchangeability.
