The Lovato 11BA1671440 is a complete AC/DC contactor coil assembly designed for Lovato B250, B310 and B400 power contactors. Supplied as an integrated replacement unit, it combines the operating coil, rectifier and coil protection components required for dependable electromagnetic contactor control.
Manufactured as an original Lovato Electric spare part, the 11BA1671440 helps restore reliable switching performance in industrial motor control and power distribution systems. Its complete assembly format simplifies maintenance by allowing technicians to replace the principal coil components together rather than sourcing and fitting separate parts.
With a rated control voltage of 440–480 V AC/DC at 50/60 Hz, the Lovato 11BA1671440 is suitable for compatible high-power contactors installed in control panels, motor starters and industrial switching equipment. Its robust construction supports reliable operation in demanding manufacturing and automation environments.
A contactor coil generates the magnetic field required to move the contactor mechanism and switch the main electrical contacts. Reliable coil operation is therefore essential for controlling motors, heaters, machinery and other high-power electrical loads.
The Lovato 11BA1671440 combines the coil, rectifier and protective components into one coordinated assembly. This helps ensure correct operation with compatible Lovato contactors while making servicing and replacement more straightforward for electrical maintenance teams.
