The Lovato 11B400SL00380 is a heavy-duty three-pole industrial power contactor designed for reliable switching of high-current electrical loads in demanding motor control and automation applications. As part of the proven Lovato B400 contactor series, this model features a 380–415 V AC/DC operating coil and is prepared for installation of the optional Lovato G495 mechanical latch.
Its latch-ready design allows panel builders and OEMs to use the contactor in standard electrically-held applications or upgrade it later with the compatible G495 mechanical latch for maintained switching. This flexibility makes it ideal for industrial machinery, motor control centres and power distribution systems.
With an IEC conventional thermal current rating of 550 A and an AC-3 operational rating of 420 A (225 kW at 400 V), the Lovato 11B400SL00380 delivers dependable performance for large three-phase motors and demanding industrial switching applications.
The Lovato 11B400SL00380 is designed to switch high-current electrical loads safely and efficiently using a low-power control circuit. Its high current capacity, robust contact system and long electrical life make it suitable for demanding industrial motor control and automation systems.
When required, the contactor can be upgraded with the optional G495 mechanical latch, allowing maintained switching without continuous coil energisation while preserving compatibility with existing control systems.
