It carries 2 normally open and 2 normally closed instantaneous contacts, rated for a 24 V 50/60 Hz coil supply.
The auxiliary contacts are rated for switching at various voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. This covers most control voltages from low-voltage DC to 690 V AC control circuits. The mechanical endurance is typical 30 million switching operations, which aligns with the SIRIUS S00 family's long-life design for high-cycle applications like conveyor interlocks or valve position feedback.
The contactor accepts solid or stranded conductors from 0.25 to 2.5 mm² per terminal, with a strip length appropriate for screw or spring-cage variants (the 3RH1122-2AB00-0TK0 uses screw terminals). Dimensions are 45 mm wide, 60 mm high, and 73 mm deep — the S00 footprint that fits standard 45 mm DIN-rail spacing, leaving room for adjacent devices in a crowded row.
The 3RH1122-2AB00-0TK0 is the 24 V 50/60 Hz coil variant of the standard 3RH1122-2AB00. The suffix -0TK0 indicates a specific packaging or documentation variant — the functional core (contacts, coil, frame) is identical to the base order code.
