Product details

It carries three normally-open (3 NO) instantaneous contacts, with no leading, lagging, or delayed switching — a straightforward make-only set for extending the contact multiplication on a main contactor or building interlock logic. Mechanically rated for 30 million switching cycles typical and shock-rated at 10 g / 5 ms and 5 g / 10 ms, it suits applications where vibration or frequent cycling is present — conveyor interlock chains, valve position feedback, or repeated machine-cycle signalling.

Mounts via screw and snap-on to DIN rail, occupying a 45 mm width, 57.5 mm height, and 72 mm depth — the compact S00 footprint that fits standard 45 mm-wide modular enclosure grids.

Auxiliary contact terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — also specified in AWG as 2x (20 to 16), 2x (18 to 14), and 1x 12. This dual-wire capacity simplifies daisy-chaining common signals without extra terminal blocks. The auxiliary switch block is extendable (product extension auxiliary switch = Yes), so additional contact blocks can be stacked on the same footprint if the 3 NO set is insufficient.

The substance prohibition (RoHS) date is July 1, 2006, indicating compliance with the EU RoHS directive on restricted substances.

Frequently asked questions

What are the key specifications of 3RH1131-1BB40-0TK0-ZX95?

It is a SIRIUS size S00 auxiliary contactor with a 24 V DC coil (3.2 W), 3 NO contacts rated 10 A, IP20 front protection, screw/snap-on DIN mounting, and dimensions 72 x 45 x 57.5 mm.

What compliance documentation does this part carry?

The part is RoHS compliant with a substance prohibition date of July 1, 2006. It carries a 6 kV surge voltage resistance rating and pollution degree 3 classification for industrial environments.

Will 3RH1131-1BB40-0TK0-ZX95 drop into a panel specified around 3RH2122-1BA40 without rewiring?

Both are SIRIUS auxiliary contactors in size S00 with the same mounting footprint, so the physical swap is straightforward. However, verify the contact configuration (3RH1131 is 3 NO; 3RH2122 may differ) and coil voltage (this unit is 24 V DC) before substitution.
