Why Choose the Lovato 11B6301000400380 Power Contactor?
The Lovato 11B6301000400380 is a heavy-duty four-pole power contactor designed for reliable 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 dependable 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, industrial heating systems and electrical distribution circuits. Its four main power poles enable simultaneous switching of four conductors, supporting three-phase systems with switched neutral connections and other four-pole configurations.
With a rated 380–415 V AC/DC operating coil, the 11B6301000400380 can be integrated into industrial control systems using either AC or DC control power. Its screw-mounted construction, bolt-connected power terminals and high insulation capability make it suitable for installation in motor control centres, industrial switchboards and heavy machinery.

Reliable Four-Pole Switching for Industrial Systems
Power contactors such as the Lovato 11B6301000400380 allow high-current electrical equipment to be switched remotely through a lower-power control circuit. Applying the specified voltage to the coil closes the four main contacts, allowing electrical power to flow to the connected load or distribution circuit.
The four-pole configuration is particularly useful where all three phase conductors and a neutral conductor must be switched simultaneously. Its high current rating, AC/DC coil and durable 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.
