The Lovato 11B180SL0048 is a heavy-duty three-pole power contactor engineered for demanding motor control and industrial switching applications. As part of the proven Lovato B180 contactor series, this model features a 48V AC/DC universal operating coil and is predisposed for the optional G495 mechanical latch, providing flexibility for applications that may require maintained-contact operation in the future.
Designed for motor control centres, industrial control panels and OEM machinery, the contactor combines high switching performance with robust construction and long mechanical life. The universal AC/DC coil simplifies control circuit design while allowing standardisation across multiple industrial installations.
With an IEC AC-3 operational current rating of 185A and an IEC AC-1 thermal current rating of 275A, the 11B180SL0048 is ideally suited for switching large three-phase motors and demanding industrial loads requiring dependable long-term operation.
The Lovato B180 series is engineered to provide dependable switching of high-power three-phase motors and industrial electrical loads. High-quality contacts, robust insulation and durable construction ensure reliable operation while minimising maintenance requirements in demanding industrial environments.
This version is supplied ready for installation of the optional G495 mechanical latch, allowing maintained-contact functionality to be added whenever required without replacing the contactor.
