£4,816.71
The Lovato 11B500400220 is a heavy-duty four-pole industrial power contactor designed for dependable switching of high-current electrical loads in motor control, automation and power-distribution applications. Part of the robust Lovato B500 contactor series, this model features a versatile 220–240 V AC/DC control coil for straightforward integration into industrial control systems.
Its four-pole configuration allows multiple power conductors to be switched simultaneously, making the contactor suitable for industrial switchboards, motor control centres, machinery panels and other high-capacity electrical installations. The screw-mounted construction provides secure installation in demanding industrial environments.
With an IEC AC-1 thermal current rating of 700 A and an AC-3 operational rating of 520 A / 290 kW at 400 V, the Lovato 11B500400220 delivers the switching capacity required for large motors, pumps, compressors, conveyors and process machinery.
Industrial contactors such as the Lovato 11B500400220 allow large motors and high-power electrical loads to be controlled through a lower-power control circuit. This supports remote operation, automated sequencing and integration with programmable controllers, overload protection and industrial safety systems.
The four-pole B500 design is particularly suitable for applications requiring simultaneous switching of several conductors. Its high current capacity and industrial construction provide dependable performance in motor control centres, production machinery and power-distribution equipment.
