The 80 V DC coil draws 3.2 W on both pick-up and hold, so there's no inrush spike to budget for on the DC supply. Mounts via screw or snap-on onto a DIN rail — the 45 mm width and 57.5 mm height fit the standard S00 footprint, so it clips into the same slot as the matching 3RT2 contactor. Depth is 72 mm, which leaves clearance behind a shallow enclosure door. ## Coil and contact ratings The coil operates between 0.8 and 1.1 times the rated voltage of 80 V DC, so it picks up reliably at 64 V and holds through 88 V. Shock resistance is 10g at 5 ms and 5g at 10 ms — enough for mounting on a machine frame or a vibrating panel backplate.","metaTitle":"Siemens 3RH1122-1BE80 SIRIUS Auxiliary Contactor, 80 V DC, 1","metaDescription":"Siemens SIRIUS 3RH1122-1BE80 auxiliary contactor, size S00, 80 V DC coil, 10 A rated current, 2 NO + 2 NC contacts, screw and snap-on mounting, IP20 front.
