The 4 W DC coil draw (closing and holding) is low enough that a 24 VDC power supply can drive several of these without derating. Mechanical life is listed at 30 million operations, which for a contactor used in a cycling application (say, a conveyor interlock or a valve position feedback) translates to years of service before wear becomes a concern. That's tight enough to pack into a shallow enclosure, but the forward clearance means you need the gland plate or door to sit at least 10 mm clear of the contactor face. Terminals accept solid or stranded wire: 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or 2× 4 mm². That covers the common control-circuit wire sizes from signal-level up to power-feed for a small contactor coil.","metaTitle":"Siemens 3RH2122-1BG40-0AA6 SIRIUS Auxiliary Contactor, S00,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH2122-1BG40-0AA6, size S00, 2 NO contacts, rated 10 A at 24 V and 230 V.
