11B400SL00220 – 3P CONTACTOR 220/240V W/O LATCH
Lovato 11B400SL00220 heavy-duty three-pole industrial contactor with 420 A AC3 operational current rating, 220–240 V AC/DC coil and compatibility with G495 mechanical latch systems for industrial motor control applications.
Why Choose the Lovato 11B400SL00220 Contactor?
The Lovato 11B400SL00220 is a heavy-duty three-pole industrial power contactor designed for dependable switching of large motors and high-current electrical loads. Part of the robust Lovato B400 contactor series, this model features a 220–240 V AC/DC operating coil and is prepared for the installation of a Lovato G495 mechanical latch.
The latch-ready configuration provides flexibility for panel builders, OEMs and industrial control engineers. The contactor can be used for conventional electrically held switching or fitted with the compatible G495 accessory when mechanically maintained operation is required. The mechanical latch is not included with this model.
With an IEC conventional free-air thermal current rating of 550 A and an AC-3 operational rating of 420 A / 225 kW at 400 V, the Lovato 11B400SL00220 provides reliable switching performance for large three-phase motors, industrial machinery and demanding power-control applications.

Reliable High-Current Switching for Industrial Systems
Industrial contactors allow large motors and high-power electrical loads to be operated through a comparatively low-power control circuit. The Lovato 11B400SL00220 supports dependable remote switching and straightforward integration with motor starters, automation systems, safety circuits and industrial control panels.
Its compatibility with the optional G495 mechanical latch allows the contactor to be adapted for maintained switching applications. When the correct latch is installed, the operated position can be retained mechanically without requiring the main contactor 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.
