It snaps onto the DIN rail and provides two contact sets: one normally open and one normally closed, plus a second NO+NC pair configured as make-before-break (1 NO + 1 NC and 1 NO + 1 NC make-before-break per EN 50005). Rated at 10 A at 24 V, it handles 6 A at 24 V, 60 V, 125 V, 230 V, and 250 V, with derated values at higher voltages: 3 A at 400 V, 0.3 A at 220 V. For AC-15 duty at 690 V, it carries 1 A. Spring-loaded terminals accept 2x (0.5 to 1.5 mm²) with ferrule, or 2x (0.5 to 2.5 mm²) solid, and 2x (20 to 14 AWG). The block is IP20 front-protected, rated for -25 to +60 °C operation and -55 to +80 °C storage.
Lifecycle — phased out, successor defined
This part is a phased-out product. The manufacturer lists it as current-stage lifecycle, but the description explicitly marks it as a phased-out product with a defined successor: the SIRIUS 3RH2911-2FB22 is the preferred replacement.
Integration — panel fit and wiring
The block measures 46 mm deep, 36.5 mm wide, and 37.5 mm high — the standard S00 footprint that fits alongside SIRIUS contactor relays and power contactors on the same DIN rail. Snap-on mounting means no tools for rail attachment; the spring-loaded terminals reduce wiring time compared to screw-clamp blocks, but verify the ferrule size against your wire gauge (0.5–1.5 mm² with ferrule, 0.5–2.5 mm² solid). This makes it suitable for high-cycle auxiliary circuits in conveyor lines, packaging machines, or pump panels where the auxiliary contacts see frequent operation.
