Why Choose the Lovato 11B6304L00220220 Power Contactor?
The Lovato 11B6304L00220220 is a heavy-duty four-pole power contactor with mechanical latch designed for reliable switching and holding of high-current electrical loads in industrial control, automation and power distribution systems. As part of the advanced Lovato B630 contactor series, it combines high current capability with a factory-fitted mechanical latch system for applications requiring secure contact position retention.
This contactor features an IEC conventional free-air thermal current rating of 800 A in AC-1 duty and an AC-3 operational rating of 630 A / 355 kW at 400 V, making it suitable for large industrial motors, distribution systems and high-power electrical loads. The four normally open main poles provide reliable switching of four conductors in demanding industrial installations.
The integrated 220–240 V AC/DC coil with fitted G495 mechanical latch allows the contactor to maintain its position without continuous coil energisation, improving efficiency and supporting specialised industrial control applications.
