The 10 A rating applies across the contact set, but the actual switching capacity depends on the voltage and duty — at 24 V it carries 6 A in AC-15 service, while at 400 V the rating drops to 3 A.
This order code is a phased-out product according to the manufacturer, with the successor being the SIRIUS 3RH2 series.
The block measures 36.5 mm wide, 37.5 mm high, and 41.5 mm deep, and snaps onto the front of a size S00 contactor — no additional DIN-rail space needed since it mounts directly on the contactor. Wiring accepts two conductors per terminal: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) with ferrule, or 2x (20 to 16) and 2x (18 to 14) AWG.
