The DC 30 V coil suits applications where the control voltage is a low-voltage DC bus, common in PLC-driven panels or battery-backed systems — confirm your control supply matches 30 VDC before wiring.","metaTitle":"Siemens 3RH6122-1BC40 SIRIUS Contactor Relay, 2NO+2NC","metaDescription":"Siemens 3RH6122-1BC40 SIRIUS contactor relay, 2 NO + 2 NC contacts, DC 30 V coil, size S00, screw terminals.
