Product details

It carries 2 normally-open and 2 normally-closed instantaneous contacts, rated for 10 A in AC-12 duty and 10 A at 24 V, with switching capability down to 1 A at 690 V. The 80 V DC coil draws 3.2 W on both pick-up and hold, so there's no inrush spike to budget for on the DC supply.

Mounts via screw or snap-on onto a DIN rail — the 45 mm width and 57.5 mm height fit the standard S00 footprint, so it clips into the same slot as the matching 3RT2 contactor. Depth is 72 mm, which leaves clearance behind a shallow enclosure door.

Coil and contact ratings

The coil operates between 0.8 and 1.1 times the rated voltage of 80 V DC, so it picks up reliably at 64 V and holds through 88 V. Shock resistance is 10g at 5 ms and 5g at 10 ms — enough for mounting on a machine frame or a vibrating panel backplate.

Frequently asked questions

Where can I buy the 3RH1122-1BE80 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing — no stock or price figures are published here.

What are the key ratings of the 3RH1122-1BE80?

It is a size S00 auxiliary contactor with an 80 V DC coil drawing 3.2 W, 2 NO + 2 NC contacts rated 10 A at 24 V and 1 A at 690 V, screw and snap-on DIN rail mounting, and IP20 front protection.

Will the 3RH1122-1BE80 drop into a panel specified around the 3RH2122-1BW40?

Both are size S00 auxiliary contactors with the same 45 x 57.5 x 72 mm footprint and screw/snap-on mounting, so the mechanical fit is identical. The deciding factor is the coil voltage: the 3RH1122-1BE80 uses 80 V DC, while the 3RH2122-1BW40 uses a different coil rating — verify your control voltage before swapping.
