11B2504SL00110 – 4P CONTACTOR 110/125V W/O LATCH
Lovato 11B2504SL00110 four-pole industrial contactor with 350A AC1 operational current rating, 110…125V AC/DC universal control coil and compatibility with optional G495 mechanical latch systems.
Why Choose the Lovato 11B2504SL00110 Four-Pole Contactor?
The Lovato 11B2504SL00110 is a heavy-duty four-pole industrial power contactor designed for reliable switching of high-current electrical loads in industrial control and power distribution systems. Part of the established Lovato B250 contactor range, it provides a conventional thermal current rating of 350 A in AC-1 duty.
This model features an electronically controlled 110–125 V AC/DC operating coil, allowing it to integrate with either alternating-current or direct-current control circuits. It is also specifically prepared for use with the optional Lovato G495 mechanical latch, providing additional flexibility for applications that require maintained contact operation.
With four main power poles, robust industrial construction and compliance with recognised IEC, UL and CSA contactor standards, the 11B2504SL00110 is suitable for panel builders, machine manufacturers and electrical engineers requiring dependable high-current switching.

Reliable High-Current Power Control
Industrial contactors allow large electrical loads to be switched using a lower-power control signal. This enables motors, heating systems, distribution circuits and production equipment to be controlled remotely through electrical panels, PLCs and automation systems.
The Lovato 11B2504SL00110 combines a high AC-1 current rating with a universal AC/DC coil. Its compatibility with the G495 mechanical latch also allows the contactor to be adapted for maintained switching applications where the selected contact position must remain mechanically held.
Typical Applications
- Industrial power distribution systems.
- Heating and resistive load control.
- Motor control centres.
- Industrial control panels and switchboards.
- OEM machinery and production equipment.
- Maintained switching systems using an optional mechanical latch.
