Reliable Coil Replacement for Industrial Contactors
The electromagnetic coil assembly provides the operating force that closes the main contactor contacts when control voltage is applied and releases them when the control circuit is switched off. A damaged or deteriorated coil assembly can cause unreliable switching, excessive operating noise, overheating or complete contactor failure.
The Lovato 11BA1546440 combines the operating coil, rectifier and protective circuitry in one coordinated replacement unit. This integrated design simplifies maintenance and helps preserve the original electrical operating characteristics of compatible Lovato B-series contactors.
