Lovato 11BA1546440 AC/DC coil assembly including coil, rectifier and coil protection for Lovato B115, B145 and B180 industrial contactors operating at 440–480 V AC/DC.
£357.17
The Lovato 11BA1546440 is a genuine AC/DC replacement coil assembly designed for compatible Lovato B115, B145 and B180 industrial contactors. Supplied as a complete replacement unit, it incorporates the operating coil, rectifier and coil-protection components required to restore dependable contactor switching performance.
Rated for a 440–480 V AC/DC control supply, the 11BA1546440 provides compatibility with both alternating-current and direct-current industrial control circuits. When powered from an AC supply, the assembly supports standard 50/60 Hz operating frequencies.
This original Lovato Electric spare part is intended for servicing selected 11B115, 11B145 and 11B180 contactors. Replacing the complete assembly helps ensure that the coil, rectifier and protective circuitry remain correctly coordinated, simplifying maintenance and supporting reliable long-term operation.
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.
