£3,361.47
The Lovato 11B400L00220C220 is a heavy-duty three-pole industrial power contactor engineered for reliable switching of high-current electrical loads in demanding motor control and automation applications. Part of the robust Lovato B400 contactor series, this model is supplied with a 220–240 V AC/DC operating coil and a factory-fitted G495 mechanical latch with 220–240 V DC control, making it ideal for maintained contact applications.
The integrated mechanical latch retains the contactor in the energised position without requiring continuous coil power, reducing energy consumption while ensuring dependable maintained switching. Its robust construction, long mechanical life and compliance with major international standards make it suitable for industrial control panels, switchgear and OEM machinery.
With an IEC AC-1 thermal current rating of 550 A and an AC-3 operational rating of 420 A (225 kW at 400 V), the 11B400L00220C220 delivers reliable performance for large three-phase motors and heavy-duty industrial loads.
The Lovato 11B400L00220C220 combines high-current switching capability with mechanically maintained operation, making it ideal for applications where continuous energisation of the contactor coil is undesirable. The G495 latch securely holds the contactor in position until released via its dedicated DC control circuit.
Its high electrical ratings, robust construction and compatibility with industrial automation systems make it suitable for demanding manufacturing, processing and power-distribution environments.
