The 125 V DC coil voltage is the critical fit parameter — it determines whether this relay picks up and seals in your DC control circuit. The 2 NO + 2 NC contact arrangement gives you two independent form-A and two form-B contact sets for interlocking, auxiliary switching, or logic feedback in a motor starter or control scheme. Multi-unit packaging (40 pieces per pack) is intended for OEM builds or scheduled panel production, not single-unit replacement. The active status means no last-time-buy pressure. This contactor relay is used in motor control centers, panel builder assemblies, and industrial automation cabinets where a DC-operated auxiliary relay is needed for contactor coil switching, PLC output interposing, or signal isolation.","metaTitle":"Siemens 3RH2122-1BG40-Z W97 Contactor Relay, 125 V DC, 2 NO","metaDescription":"Siemens contactor relay 3RH2122-1BG40-Z W97, 125 V DC coil, 2 NO + 2 NC contacts, screw terminal, frame size S00.
