The Lovato 11B630100000440 is a heavy-duty three-pole power contactor designed for switching high-current electrical loads in industrial motor control, power distribution and automation systems. Part of the robust Lovato B Series contactor range, this model combines a high current capacity with dependable electromagnetic switching for demanding industrial applications.
With an IEC conventional free-air thermal current rating of 1000 A in AC-1 duty, the contactor is suitable for controlling resistive loads, heating equipment and other high-power circuits. Its three normally open main poles provide reliable isolation and switching, while the electronically controlled coil can operate from either AC or DC control supplies.
The 11B630100000440 features a 440–480 V AC/DC coil, making it suitable for industrial control systems using high control voltages. Screw fixing and heavy-duty power terminals enable secure installation inside switchboards, motor control centres and industrial electrical panels.
Power contactors such as the Lovato 11B630100000440 provide remote electrical switching for motors, heating circuits and other high-current industrial loads. Applying the specified control voltage to the coil closes the three main contacts, allowing power to flow to the connected equipment.
The contactor’s high current rating, strong making capacity and long operating life make it suitable for applications where frequent and dependable switching is essential. Its AC/DC coil offers additional control-system flexibility, while EMC compatibility supports integration into modern industrial installations.
