11B250L00110110 – 3P CONTACTOR 110/125V C/W LATCH 110VAC
Lovato 11B250L00110110 three-pole industrial contactor with integrated G495 mechanical latch, 265A AC3 operational current rating and 110…125V AC/DC universal control coil for industrial automation and motor control systems.
Why Choose the Lovato 11B250L00110110 Three-Pole Mechanically Latched Contactor?
The Lovato 11B250L00110110 is a heavy-duty three-pole industrial power contactor engineered for reliable switching of high-current electrical loads in demanding industrial applications. Part of the proven Lovato B250 contactor series, this model is factory-fitted with a G495 mechanical latch, enabling the contactor to remain energised without continuous coil power.
The contactor features a universal 110–125 V AC/DC operating coil together with a 110–125 V AC mechanical latch, making it ideal for applications requiring maintained switching, reduced control power consumption and dependable load isolation. Its robust construction provides excellent electrical endurance, high insulation performance and long mechanical life.
With an IEC conventional thermal current rating of 350 A (AC-1), an AC-3 operational current of 265 A and three normally open main poles, the 11B250L00110110 is ideally suited to industrial motor control, power distribution and heavy-duty automation systems.
