Why Choose the Lovato 11B630L00220110 Power Contactor?
The Lovato 11B630L00220110 is a heavy-duty three-pole power contactor with integrated mechanical latch designed for reliable switching and maintained contact positioning in industrial motor control, automation and power distribution systems. As part of the robust Lovato B630 contactor series, it combines high current switching capability with an energy-efficient latching solution for demanding industrial applications.
This contactor provides an IEC thermal current rating of 800 A in AC-1 duty and an IEC AC-3 operational rating of 630 A / 355 kW at 400 V, making it suitable for large industrial motors, electrical distribution systems and high-power switching applications. Its three normally open main poles provide dependable control of three-phase loads.
The integrated 220–240 V AC/DC coil with fitted G495 mechanical latch allows the contactor to maintain its operating position without continuous coil energisation. The mechanical latch operates with a 110–125 V AC control supply, providing a flexible solution for specialised industrial control systems.
