Why Choose the Lovato 11B6301000400220 Power Contactor?
The Lovato 11B6301000400220 is a heavy-duty four-pole power contactor designed for reliable switching of high-current electrical loads in industrial control, automation and power distribution systems. As part of the robust Lovato B6301000 contactor series, it is engineered for applications requiring substantial current capacity, dependable operation and long service life.
This contactor provides an IEC conventional free-air thermal current rating of 1000 A in AC-1 duty, making it suitable for resistive loads, industrial heating systems and other high-power electrical circuits. Its four normally open main poles enable simultaneous switching of four conductors, supporting three-phase systems that require neutral isolation or other four-pole configurations.
With an electronically controlled 220–240 V AC/DC coil, the 11B6301000400220 offers flexible integration into both AC and DC industrial control circuits. Its screw-mounted construction, bolt-connected power terminals and high insulation capability make it suitable for installation in motor control centres, switchboards and heavy industrial machinery.

Reliable Four-Pole Switching for Industrial Systems
Power contactors such as the Lovato 11B6301000400220 allow high-current equipment and distribution circuits to be switched remotely using a lower-power control signal. Applying the specified voltage to the coil closes all four main contacts, allowing electrical power to flow to the connected load.
The four-pole configuration is particularly useful when an installation requires simultaneous switching of three phase conductors and a neutral conductor. Its high current rating, AC/DC coil and robust power connections support dependable integration into motor control centres, industrial switchboards and automated production equipment.
Typical Applications
- Industrial motor control centres.
- Four-wire power distribution systems.
- High-power electrical heating equipment.
- Industrial switchboards and control panels.
- Heavy machinery and production equipment.
- Renewable energy and photovoltaic installations.
