11B2504SL00220 – 4P CONTACTOR 220/240V W/O LATCH
Lovato 11B2504SL00220 four-pole industrial contactor with 350A AC1 operational current rating, 220…240V AC/DC universal control coil and compatibility with optional G495 mechanical latch systems.
Why Choose the Lovato 11B2504SL00220 Four-Pole Contactor?
The Lovato 11B2504SL00220 is a heavy-duty four-pole industrial power contactor designed for dependable switching of high-current electrical loads in power distribution, automation and machinery-control systems. Part of the established Lovato B250 contactor series, it is engineered for panel builders, OEM manufacturers and electrical professionals requiring reliable industrial load control.
This model features an electronically controlled 220–240 V AC/DC operating coil, allowing it to integrate with either alternating-current or direct-current control circuits. It is also specifically prepared for installation of the optional Lovato G495 mechanical latch, providing additional flexibility for applications requiring mechanically maintained contact operation.
With a conventional thermal current rating of 350 A in AC-1 duty, an AC-3 operational current of 265 A and four main power poles, the 11B2504SL00220 provides robust switching performance for industrial motors, heating loads and high-current electrical circuits.

Reliable High-Current Power Control
Industrial contactors allow high-current electrical loads to be switched using a lower-power control signal. This enables motors, heating equipment, distribution circuits and production machinery to be operated remotely through control panels, PLCs and automated control systems.
The Lovato 11B2504SL00220 combines a high switching capacity with a flexible AC/DC coil. Its compatibility with the optional G495 mechanical latch also allows it to be adapted for maintained switching applications where the contactor must remain mechanically held after the control signal is removed.
Typical Applications
- Industrial power distribution systems.
- Motor control centres.
- Heating and resistive load switching.
- Industrial control panels and switchboards.
- OEM machinery and production equipment.
- Maintained switching systems using an optional mechanical latch.
