11B250L00220220 – 3P CONTACTOR 220/240V C/W LATCH 220VAC
Lovato 11B250L00220220 three-pole industrial contactor with integrated G495 mechanical latch, 265A AC3 operational current rating and 220…240V AC/DC universal control coil for industrial automation and motor control systems.
Why Choose the Lovato 11B250L00220220 Three-Pole Mechanically Latched Contactor?
The Lovato 11B250L00220220 is a heavy-duty three-pole industrial power contactor designed for dependable switching of high-current electrical loads in motor control, automation and power distribution systems. As part of the established Lovato B250 contactor series, it is engineered for panel builders, OEM machine manufacturers and industrial electrical professionals.
This contactor features an electronically controlled 220–240 V AC/DC operating coil and is supplied with a factory-fitted Lovato G495 mechanical latch. The 220–240 V AC latch mechanism allows the contactor to remain mechanically held after the operating signal is removed, reducing continuous control-coil power consumption.
With an AC-3 operational current rating of 265 A, a conventional thermal current of 350 A and three normally open main poles, the 11B250L00220220 is suitable for controlling large three-phase motors and high-current industrial circuits requiring reliable maintained contact operation.

Reliable Mechanically Latched Power Switching
Mechanically latched contactors remain in their selected operating position after the initial control signal has been removed. This reduces continuous coil power consumption and helps maintain the required switching state during temporary interruptions to the control supply.
The Lovato 11B250L00220220 combines a high-current B250 contactor with a factory-installed G495 latch. This makes it particularly suitable for applications in which a three-phase load must remain connected until a deliberate release command is applied.
Typical Applications
- Industrial motor control centres.
- Power distribution and switchgear systems.
- Load-shedding and energy-management equipment.
- Pumps, fans and conveyor systems.
- Industrial automation and production machinery.
- Applications requiring maintained contactor operation.
