11B2504L00220220 – 4P CONTACTOR 220/240V C/W LATCH 220VAC
Lovato 11B2504L00220220 four-pole industrial contactor with integrated mechanical latch, 350A AC1 operational current rating and 220…240V AC/DC universal control coil for industrial automation and power switching systems.
Why Choose the Lovato 11B2504L00220220 Four-Pole Mechanically Latched Contactor?
The Lovato 11B2504L00220220 is a heavy-duty four-pole industrial power contactor designed for reliable switching of high-current electrical loads in demanding industrial applications. Part of the proven Lovato B250 contactor series, this model is supplied with a factory-fitted G495 mechanical latch, allowing the contactor to remain in its operating position without continuous coil energisation.
The contactor features a universal 220–240 V AC/DC operating coil and a matching 220–240 V AC mechanical latch, making it ideal for applications requiring maintained switching, energy-saving operation and dependable load isolation. Its robust design delivers excellent electrical endurance, high insulation performance and long mechanical life.
With a conventional thermal current rating of 350 A (AC-1), an AC-3 operational current of 265 A and four normally open main poles, the 11B2504L00220220 is suitable for power distribution, industrial automation, heating systems and high-current switching applications.
