The Lovato 11B630400220 is a heavy-duty four-pole power contactor designed for dependable switching of high-current electrical loads in industrial control, automation and power distribution systems. As part of the robust Lovato B630 contactor series, it is engineered for demanding installations requiring substantial current capacity, secure electrical connections and reliable long-term performance.
This contactor provides an IEC conventional free-air thermal current rating of 800 A in AC-1 duty, making it suitable for high-power resistive loads, industrial heating equipment and electrical distribution circuits. Its four normally open main power poles enable four conductors to be switched simultaneously, supporting three-phase systems with switched neutral connections and other four-pole configurations.
With an electronically controlled 220–240 V AC/DC operating coil, the 11B630400220 offers flexible integration into both AC and DC industrial control circuits. Its screw-mounted construction, high insulation capability and robust industrial design make it suitable for installation in motor control centres, switchboards and heavy machinery.
Power contactors such as the Lovato 11B630400220 allow high-current equipment to be controlled remotely through a lower-power electrical control circuit. Applying the specified voltage to the contactor coil closes all four main contacts, allowing electrical power to flow to the connected machinery or distribution circuit.
The four-pole configuration is particularly useful when three phase conductors and a neutral conductor must be switched simultaneously. Its high current capacity, AC/DC coil and durable construction support dependable integration into industrial switchboards, motor control centres and automated production systems.
