11B400SL00110 – 3P CONTACTOR 110/125V W/O LATCH
Lovato 11B400SL00110 heavy-duty three-pole industrial contactor with 400 A AC3 operational current rating and 110 V AC operating coil for industrial motor control applications.
Why Choose the Lovato 11B400SL00110 Contactor?
The Lovato 11B400SL00110 is a heavy-duty three-pole industrial power contactor designed for reliable switching of large motors and high-current electrical loads. Part of the robust Lovato B400 contactor series, this model features a 110–125 V AC/DC operating coil and is specially prepared for installation of the Lovato G495 mechanical latch.
The latch-ready design gives panel builders, OEMs and industrial control engineers the flexibility to add mechanically maintained switching when required. This model is supplied without the mechanical latch, allowing it to operate as a conventional contactor or to be upgraded using the compatible G495 accessory.
With an IEC AC-3 operational rating of 420 A and 225 kW at 400 V, the Lovato 11B400SL00110 provides dependable switching performance for large three-phase motors, process machinery and demanding industrial power-control systems.

Reliable High-Current Switching for Industrial Systems
Industrial contactors allow large motors and high-power electrical loads to be controlled using a comparatively low-power control circuit. The Lovato 11B400SL00110 provides the switching capacity needed for demanding motor-control applications while supporting integration with automated machinery, motor control centres and industrial switchboards.
Its compatibility with the optional G495 mechanical latch also enables the contactor to be adapted for maintained switching. Once the appropriate latch is installed, the contactor can retain its operated position mechanically without requiring the main coil to remain continuously energised.
Typical Applications
- Large three-phase industrial motor starters.
- Motor control centres and industrial switchboards.
- Pumps, compressors and ventilation equipment.
- Conveyors and material-handling machinery.
- Industrial process and production equipment.
- Maintained switching systems using an optional G495 latch.
