Why Choose the Lovato 11B2504L00110C110 Four-Pole Contactor?
The Lovato 11B2504L00110C110 is a heavy-duty four-pole industrial power contactor designed for reliable switching of high-current electrical loads. Part of the established Lovato B250 contactor series, it is supplied with a factory-fitted mechanical latch for applications that require the contactor to remain in its operating position without continuous coil energisation.
This contactor features an electronically controlled 110–125 V AC/DC operating coil and an integrated Lovato G495 mechanical latch. The latch is released using a separate 110–125 V DC unlatching coil, making the unit suitable for power distribution, energy management and industrial control systems where maintained switching is required.
With a conventional thermal current rating of 350 A in AC-1 duty and four main power poles, the 11B2504L00110C110 provides dependable control of resistive loads and high-current electrical circuits. Its robust construction, high insulation performance and mechanically latched operation make it suitable for demanding industrial installations.

Reliable Mechanically Latched Power Switching
Mechanically latched contactors remain in their selected operating position after the control signal has been removed. This can reduce control-coil energy consumption and prevent unwanted contactor release during temporary control-voltage interruptions.
The Lovato 11B2504L00110C110 uses separate electrical commands for closing and releasing the contactor. Its 110–125 V AC/DC operating coil closes the main contacts, while the 110–125 V DC release coil disengages the mechanical latch when the circuit must be opened.
Typical Applications
- Industrial power distribution systems.
- Load-shedding and energy-management equipment.
- Capacitor bank and resistive load switching.
- Emergency power and transfer-control systems.
- Industrial control panels and switchboards.
- Applications requiring maintained contactor operation.
