Why Choose the Lovato 11B4004L00220C220 Contactor?
The Lovato 11B4004L00220C220 is a heavy-duty four-pole industrial contactor designed for dependable switching of high-current electrical loads in motor control, automation and power distribution systems. Part of the robust Lovato B400 contactor series, it combines a 220–240 V AC/DC operating coil with a factory-fitted G495 mechanical latch.
The mechanical latch is operated by a separate 220–240 V DC release circuit, enabling the contactor to maintain its switching position without continuous energisation of the main operating coil. This makes the unit particularly suitable for maintained-control applications where reduced coil consumption and secure contact retention are required.
With an IEC thermal current rating of 550 A in AC-1 duty and an operational rating of 420 A / 225 kW at 400 V in AC-3 duty, the 11B4004L00220C220 is suitable for large industrial motors, resistive loads and demanding electrical switching installations.

Reliable Maintained Switching for Industrial Systems
Industrial contactors switch motors and other high-power loads using a comparatively low-power control circuit. The Lovato 11B4004L00220C220 adds a mechanical latching mechanism that physically retains the contactor position after operation, reducing the need to keep the main coil continuously energised.
Its combination of high-current switching capacity, separate DC latch control and four normally open power poles makes it well suited to motor control centres, process equipment, power distribution panels and automated machinery requiring stable maintained switching.
Typical Applications
- Large industrial motor starters and control systems.
- Maintained switching and latching control circuits.
- Motor control centres and industrial switchboards.
- High-current resistive load switching.
- Industrial automation and process machinery.
- Power distribution and changeover installations.
