Product details

It mounts via screw and snap-on onto 35 mm DIN rail, with a width of 45 mm, depth of 117 mm, and height of 57.5 mm — fits standard panel layouts without crowding adjacent devices. Rated switching currents span from 10 A at 24 V up to 0.26 A at 600 V, with intermediate ratings at 60 V (4.7 A), 110 V (3 A), 220 V (1.2 A), 230 V (6 A), 400 V (3 A), 440 V (0.5 A), 500 V (2 A), and 690 V (1 A).

Pollution degree 3 (industrial environment with conductive or dry non-conductive pollution).

Switching Performance and Wiring

Arcing time on AC loads runs 4 to 15 ms; maximum switching frequency on DC is 10,000 operations per hour. Rated voltage tolerance: 0.8–1.1 x rated value at 50 Hz, 0.85–1.1 at 60 Hz. Relative humidity minimum 10%. Substance prohibition date: 07/01/2006.

Frequently asked questions

Will 3RH2344-1CL00 drop into a panel that was specified around 3RH2362-2AF00 without rewiring?

Both are SIRIUS auxiliary contactors in size S00 with the same DIN-rail footprint, so panel cut-out and rail spacing are identical. The 3RH2344-1CL00 carries 4 NO contacts; the 3RH2362-2AF00 has a different contact configuration — verify your circuit's contact count and wiring before substitution.

What compliance documentation does this brand provide for 3RH2344-1CL00 (RoHS, REACH, UL, IEC)?

The part carries a substance prohibition date of 07/01/2006, aligning with RoHS/REACH compliance. The SIRIUS series typically holds UL, CSA, and IEC certifications; specific mark listings should be confirmed from the nameplate or manufacturer declaration.
