£1,870.61
The Lovato 11B250SL0048 is a heavy-duty three-pole industrial power contactor designed for reliable 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 48 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 11B250SL0048 is suitable for controlling large three-phase motors and demanding industrial electrical loads.
Industrial contactors such as the Lovato 11B250SL0048 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.
