Lovato 11B400L00110C110 heavy-duty three-pole industrial contactor with 420 A AC3 operational current rating, AC/DC coil and integrated mechanical latch for industrial motor control and automation systems.
£3,361.47
The Lovato 11B400L00110C110 is a heavy-duty three-pole industrial power contactor designed for reliable switching of large motors and high-current electrical loads. Part of the robust Lovato B400 contactor series, it features a 110–125 V AC/DC operating coil and is supplied with a factory-fitted Lovato G495 mechanical latch.
The mechanical latch is operated by a separate 110–125 V DC control circuit, allowing the contactor to remain mechanically engaged after the operating coil has been de-energised. This maintained switching arrangement reduces the need for continuous coil energisation and supports secure operation in industrial control and power-distribution systems.
With an IEC AC-3 operational rating of 420 A and 225 kW at 400 V, the Lovato 11B400L00110C110 provides the switching capacity required for large three-phase motors, process machinery, pumps, compressors and other demanding industrial loads.
Industrial contactors allow large motors and other high-power electrical loads to be controlled through a lower-power control circuit. The Lovato 11B400L00110C110 adds a mechanical latching mechanism that physically retains the contactor in its operated position after the main coil has been de-energised.
Its high AC-3 switching capacity, three-pole configuration and separate DC latch circuit make it suitable for motor control centres, automated machinery and power-control systems requiring stable maintained operation and reduced continuous coil consumption.
