The Lovato 11B630L00110110 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 AC-3 operational current rating of 630 A at 400 V with a corresponding motor switching capacity of 355 kW. Its three normally open main poles provide dependable control of high-power three-phase loads, while the fitted G495 mechanical latch maintains the contactor position without requiring continuous coil energisation.
The integrated 110–125 V AC/DC coil and mechanical latch system make the 11B630L00110110 suitable for applications where reliable switching states and reduced control power consumption are required. Its industrial construction supports installation in motor control centres, switchboards and heavy-duty automation systems.
The Lovato 11B630L00110110 provides reliable control of high-power electrical loads while reducing the need for continuous coil energisation. The integrated mechanical latch maintains the contactor position after operation, making it suitable for systems requiring stable switching states.
Its combination of three-pole switching, high AC-3 current capability, AC/DC coil operation and mechanical retention makes it ideal for industrial motor control, power distribution and automation applications.
