The LOVATO Electric 11B4000060 is a heavy-duty three-pole industrial power contactor designed for reliable switching and control of large three-phase motors and other high-current electrical loads. As part of the robust LOVATO B400 contactor series, it provides an IEC operational current rating of 420 A in AC-3 duty, making it suitable for demanding industrial motor-control and 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 high switching capacity, durable construction and secure screw-mounted design support dependable installation in motor control centres, industrial switchboards, production machinery and process-control systems.
With a conventional free-air thermal current rating of 550 A in AC-1 duty and a motor rating of 225 kW at 400 V AC-3, the 11B4000060 is engineered for applications requiring consistent high-power switching. Its high insulation performance and compliance with recognised IEC, UL and CSA standards further support its use in industrial electrical systems and OEM equipment.
Industrial contactors use a relatively low-power electrical control signal to switch high-current motor and power circuits. When the contactor coil is energised, the three main contacts close simultaneously, supplying power to the connected three-phase load. This allows motors and machinery to be operated remotely through PLCs, pushbuttons, control relays and automated control systems.
The LOVATO Electric B400 series is designed for demanding industrial installations where high current capacity and dependable switching performance are essential. The 11B4000060 combines a 420 A AC-3 rating with a 60 V AC/DC coil, providing a practical solution for large motors, industrial machinery and process equipment.
