£3,679.49
The LOVATO Electric 11B40040060 is a heavy-duty four-pole industrial power contactor designed for dependable switching of high-current electrical loads. As part of the robust LOVATO B400 contactor series, it provides an IEC conventional free-air thermal current rating of 550 A in AC-1 duty, making it suitable for demanding power distribution, heating, lighting and industrial automation applications.
This contactor features a versatile 60 V AC/DC control coil, enabling operation from compatible alternating-current or direct-current control supplies. Its four-pole configuration allows four conductors to be switched simultaneously, making it particularly useful in three-phase systems requiring neutral switching or complete multipole circuit isolation.
With an operational current rating of 420 A in AC-3 duty and a motor power rating of 225 kW at 400 V, the 11B40040060 delivers the capacity required for large motors and industrial power circuits. Its high insulation rating, secure screw mounting and compliance with recognised international standards support reliable installation in switchboards, motor control centres and heavy-duty machinery.
Four-pole contactors allow four high-current conductors to be switched simultaneously using a comparatively low-power electrical control signal. When the control coil is energised, all four main contacts operate together, enabling remote control through PLCs, relays, timers, pushbuttons and automated industrial control systems.
The LOVATO Electric 11B40040060 is particularly suitable for AC-1 applications involving resistive or slightly inductive loads, including electric heating, lighting and power-distribution circuits. Its 420 A AC-3 rating also supports the control of large three-phase motors in industrial machinery and automated production equipment.
