Why Choose the Lovato 11B6301000400440 Power Contactor?
The Lovato 11B6301000400440 is a heavy-duty four-pole power contactor designed for dependable switching of high-current electrical loads in industrial motor control, automation and power distribution systems. As part of the robust Lovato B6301000 contactor series, it is engineered for demanding installations that require substantial current capacity, secure electrical connections and reliable long-term performance.
This contactor provides an IEC conventional free-air thermal current rating of 1000 A in AC-1 duty, making it suitable for high-power resistive loads, electrical heating equipment and industrial distribution circuits. Its four normally open main poles allow four conductors to be switched simultaneously, supporting three-phase systems with a switched neutral and other four-pole applications.
With an electronically controlled 440–480 V AC/DC coil, the 11B6301000400440 offers flexible operation from either AC or DC industrial control supplies. 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 11B6301000400440 allow high-current electrical equipment to be switched remotely using a lower-power control circuit. Applying the specified control voltage to the coil closes all four main contacts, allowing electrical power to flow to the connected load or distribution circuit.
The four-pole configuration is particularly useful where three phase conductors and a neutral conductor must be switched simultaneously. Its high current rating, AC/DC coil and robust construction support reliable integration into industrial switchboards, motor control centres 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.
