11B250L00110C110 – 3P CONTACTOR 110/125V C/W LATCH 110VDC
Lovato 11B250L00110C110 three-pole industrial contactor with integrated G495 mechanical latch, 265A AC3 operational current rating and 110…125V AC/DC universal control coil for industrial automation and motor control systems.
Why Choose the Lovato 11B250L00110C110 Three-Pole Mechanically Latched Contactor?
The Lovato 11B250L00110C110 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 110–125 V AC/DC operating coil and is supplied with a factory-fitted Lovato G495 mechanical latch. A dedicated 110–125 V DC release coil disengages the latch, allowing the contactor to provide maintained switching without requiring continuous energisation of the main operating coil.
With an AC-3 rated operational current of 265 A, three normally open main poles and a mechanically latched design, the 11B250L00110C110 is suitable for controlling large three-phase motors and high-current industrial circuits where reliable maintained contact operation is required.

- Screw-mounted construction for industrial control panels.
- Suitable for maintained switching of high-current loads.
Reliable Mechanically Latched Power Switching
Mechanically latched contactors remain in their selected operating position after the closing 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 11B250L00110C110 uses separate electrical commands for closing and releasing the contactor. The 110–125 V AC/DC operating coil closes the main contacts, while the dedicated 110–125 V DC release coil disengages the mechanical latch when the controlled circuit needs to be opened.
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.
