The Lovato 11B500400380 is a heavy-duty four-pole industrial power contactor engineered for dependable switching of high-current electrical loads in motor control, automation and power-distribution systems. Part of the robust Lovato B500 contactor series, this model features a 380–415 V AC/DC operating coil for integration into industrial control circuits.
Its four-pole configuration enables multiple power conductors to be switched simultaneously, making it suitable for industrial switchboards, motor control centres, OEM machinery and high-capacity electrical installations. Heavy-duty terminals, screw mounting and a broad operating-temperature range support reliable use in demanding industrial environments.
With an IEC conventional free-air thermal current rating of 700 A and an AC-3 operational rating of 520 A / 290 kW at 400 V, the Lovato 11B500400380 provides the switching capacity required for large motors, pumps, compressors, conveyors and process machinery.
Industrial contactors such as the Lovato 11B500400380 allow large motors and other high-power electrical loads to be controlled through a lower-power control circuit. This supports remote switching, automated sequencing and integration with programmable controllers, overload protection and industrial safety systems.
The four-pole B500 design is particularly suitable for installations requiring simultaneous control of multiple conductors. Its high switching capacity, robust construction and long operational life provide dependable performance in industrial motor control centres, switchboards and process machinery.
