11B3100060 – 3P CONTACTOR B310.00 60V
Lovato 11B3100060 three-pole industrial contactor with 320A AC3 operational current rating and 60V AC/DC control coil for industrial motor control and automation systems.
Why Choose the LOVATO Electric 11B3100060 Three-Pole Contactor?
The LOVATO Electric 11B3100060 is a heavy-duty three-pole industrial power contactor designed for dependable switching and control of large three-phase motors and high-current electrical loads. As part of the robust LOVATO B310 contactor range, it provides an IEC operational current rating of 320 A in AC-3 duty, making it suitable for demanding motor-control and industrial automation applications.
This contactor features a versatile 60 V AC/DC control coil, enabling integration with compatible alternating-current and direct-current control systems. Its high electrical capacity, robust construction and screw-mounted design support reliable operation in motor control centres, switchboards, production machinery and process-control installations.
With a motor rating of up to 170 kW at 400 V AC-3 and a conventional free-air thermal current of 450 A, the 11B3100060 is engineered for applications requiring consistent high-power switching. Compliance with recognised IEC, UL and CSA standards further supports its use in industrial electrical systems and OEM machinery.

Reliable High-Current Motor Control
Industrial contactors allow a 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 enables safe remote operation through PLCs, pushbuttons, control relays and automated machine-control systems.
The LOVATO Electric B310 series is designed for demanding industrial installations where high current capacity and dependable switching performance are essential. The 11B3100060 combines a 320 A AC-3 rating with a 60 V AC/DC coil, providing a practical solution for large motors, industrial machinery and process equipment.
