It carries a 24 VAC 60 Hz coil and is rated for 10 A at 24 V, with a maximum operating voltage of 480 V at 60 Hz. The contactor mounts via screw or snap-on onto a 35 mm standard DIN rail, fitting into the compact S00 footprint (45 mm wide, 57.5 mm tall, 73 mm deep).
Coil and switching ratings
The coil is wound for 24 VAC at 60 Hz, with an operating range of 0.85 to 1.1 times the rated value at 60 Hz. This means the coil reliably picks up between about 20.4 V and 26.4 V at 60 Hz. For DC loads, the rated currents drop significantly with voltage: 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, and 0.26 A at 600 V. These are the DC-13 (or similar inductive) ratings — the actual switching capacity depends on the load time constant.
The S00 size keeps the panel footprint tight, but those clearances must be maintained for arc flash and heat dissipation.
The 3RH2122-1AV60 is a current-production part (lifecycle stage: current).
