Why Choose the Lovato 11B2504L00220C220 Four-Pole Mechanically Latched Contactor?
The Lovato 11B2504L00220C220 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 220–240 V AC/DC operating coil and an integrated Lovato G495 mechanical latch. The latch is released using a dedicated 220–240 V DC release coil, making the unit suitable for energy management, power distribution and industrial control systems requiring maintained switching.
With an IEC conventional thermal current rating of 350 A in AC-1 duty and four main power poles, the 11B2504L00220C220 provides dependable switching for resistive loads and high-current electrical circuits. Its robust construction 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 closing control signal has been removed. This reduces continuous coil energy consumption and helps maintain the switching state during temporary control-voltage interruptions.
The Lovato 11B2504L00220C220 uses separate electrical commands for closing and releasing the contactor. Its 220–240 V AC/DC operating coil closes the main contacts, while the dedicated 220–240 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.
- Resistive load and heating-system switching.
- Emergency power and transfer-control systems.
- Industrial control panels and switchboards.
- Applications requiring maintained contactor operation.
