Reliable Contactor Control for Industrial Systems
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.
