Product details

It's rated 10 A at AC-12 (resistive) and carries a surge voltage withstand of 6 kV, making it a straightforward signal-level switching block for control circuits inside a panel.

The 45 mm width and 57.5 mm height fit the standard S00 footprint — same envelope as the 3RT10 contactor family, so it shares the same rail space and wiring troughs. Depth is 72 mm, which leaves clearance behind a 100 mm deep enclosure backplate.

Coil and contact ratings

Coil holds at 24 VDC nominal; closing and holding power are both 3.2 W. The three NO contacts are rated 10 A at AC-12, with inductive load break capacities dropping to 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. DC switching is also specified: 10 A at 24 V, 1 A at 110 V, and 0.27 A at 220 V.

Frequently asked questions

Will the 3RH1131-1BB40-ZX95 drop into a panel built for the 3RT1015-1BB42?

Both are Size S00 with the same 45 mm width and DIN-rail mounting, so the mechanical fit is identical. The 3RH1131-1BB40-ZX95 is an auxiliary contactor (3 NO, 24 VDC coil), while the 3RT1015-1BB42 is a power contactor with a different coil voltage and contact configuration — they are not electrically interchangeable, but they share the same footprint.
