Why Choose the Lovato 11B4004SL00110 Contactor?
The Lovato 11B4004SL00110 is a heavy-duty four-pole industrial contactor designed for reliable switching of high-current electrical loads in motor control, automation and power distribution systems. Part of the robust Lovato B400 contactor series, this model features a 110–125 V AC/DC control coil and is prepared for the installation of a Lovato G495 mechanical latch.
Unlike factory-latched variants, the 11B4004SL00110 is supplied without the mechanical latch installed. Its latch-ready construction allows the appropriate G495 accessory to be added when maintained switching is required, providing flexibility for panel builders, OEMs and industrial control engineers.
With an IEC thermal current rating of 550 A in AC-1 duty and an operational rating of 420 A / 225 kW at 400 V in AC-3 duty, this contactor is suitable for controlling large industrial motors, resistive loads and high-capacity electrical distribution circuits.

Reliable High-Current Switching for Industrial Systems
Industrial contactors such as the Lovato 11B4004SL00110 allow large motors and electrical loads to be controlled through a lower-power control circuit. This helps provide dependable remote switching, integration with automation systems and safe coordination with overload and short-circuit protection devices.
The contactor’s compatibility with the G495 mechanical latch also allows it to be adapted for maintained switching applications. Once the optional latch is installed, the switching position can be retained mechanically without requiring the operating coil to remain continuously energised.
Typical Applications
- Large industrial motor starters.
- Motor control centres and switchboards.
- Industrial automation and process machinery.
- High-current resistive load switching.
- Power distribution and control panels.
- Maintained switching systems using an optional G495 latch.
