MPN: 3RH1140-1BB40 — industrial control spare part, in stock at TGK Parts.
The 3RH1140-1BB40 is the 4 NO contactor relay of the SIRIUS 3RH1 family with a 24 VDC coil — the interface relay between PLC outputs and contactor coils in essentially every Siemens-based control panel. Its ubiquity makes it one of the highest-volume control components in the surplus market.
Coil resistance, contact resistance and pick-up voltage are verified on every unit; units with pitted or welded contacts are scrapped.
