Product details

Rated for a maximum of 10 A, with switching capacity derated by voltage: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. The AC-15 rating at 690 V is 1 A.

Key electrical and mechanical ratings

Connections are screw-type terminals accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core-end processing, or 2x (20 to 16) and 2x (18 to 14) AWG.

Physical dimensions and mounting

Dimensions are 36.5 mm wide, 37.5 mm high, and 41.5 mm deep — a compact footprint that fits alongside SIRIUS contactors on the same DIN rail without exceeding the panel depth budget.

Frequently asked questions

What replaces the 3RH1911-1GA22-ZW98?

The official successor is the SIRIUS 3RH2 series auxiliary switch block. The 3RH2 family offers the same 2 NO + 2 NC contact configuration and snap-on mounting but with updated design.

What are the key ratings for this auxiliary switch block?

Maximum 10 A, with derated values per voltage: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. AC-15 rating at 690 V is 1 A. Mechanical life is 10 million cycles.

Will the 3RH1911-1GA22-ZW98 fit a panel designed for the 3RT1015-1BB42 contactor?

Yes, both use snap-on mounting onto 35 mm DIN rail per EN 50022. The auxiliary switch block is designed as a side-mount add-on for SIRIUS contactors like the 3RT1015 series. Verify the contactor's auxiliary contact slot compatibility, but the mounting rail and footprint are standard.
