11B250SL0024 – 3P CONTACTOR 24V W/O LATCH
Lovato 11B250SL00220 three-pole industrial contactor with 265A AC3 operational current rating, 220…240V AC/DC universal control coil and compatibility with optional G495 mechanical latch systems.
Why Choose the Lovato 11B250SL0024 Three-Pole Contactor?
The Lovato 11B250SL0024 is a heavy-duty three-pole industrial power contactor designed for dependable switching of high-current electrical loads in motor control, automation and power distribution systems. Part of the established Lovato B250 contactor series, it is engineered for panel builders, OEM machine manufacturers and industrial electrical professionals.
This contactor features an electronically controlled 24 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 flexibility for applications requiring mechanically maintained contact operation.
With an IEC operational current rating of 265 A in AC-3 duty, a conventional thermal current rating of 350 A and a 140 kW motor rating at 400 V, the 11B250SL0024 is suitable for controlling large three-phase motors and demanding industrial electrical loads.

Reliable High-Current Motor Control
Industrial contactors such as the Lovato 11B250SL0024 allow large three-phase loads to be controlled using a lower-power switching signal. This enables motors, pumps, compressors, conveyors and production machinery to be operated remotely through PLCs, control relays and automated electrical panels.
The electronically controlled AC/DC coil provides flexible integration with different control-power systems. Compatibility with the optional 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 motor control centres.
- Pumps, compressors and ventilation systems.
- Conveyor and material-handling equipment.
- Industrial automation and production machinery.
- Power distribution panels and switchgear.
- Maintained switching systems using an optional mechanical latch.
