Lovato 11B115400110 is a B115 four-pole power contactor with four normally open contacts, a 160 A AC-1 rating and a 110–125 V AC/DC control coil for high-current industrial switching.
Original price was: £776.33.£543.43Current price is: £543.43.
The Lovato 11B115400110 is a heavy-duty four-pole power contactor designed for switching high-current electrical loads in industrial control and automation systems. As part of the Lovato B Series, this B115 contactor combines four main poles with robust electrical and mechanical performance for demanding applications.
Its four normally open main contacts provide a conventional free-air thermal current rating of 160 A. The contactor supports AC-1 loads rated at 160 A at temperatures up to 40 °C, making it suitable for resistive heating, lighting, power distribution and other non-inductive load-switching duties.
The 11B115400110 features an AC/DC coil rated from 110–125 V, allowing operation from either AC or DC control circuits. Screw mounting, high-capacity power terminals and a mechanical life of 10,000,000 operating cycles support reliable integration into industrial electrical panels.
Four-pole contactors enable several conductors or circuits to be switched simultaneously from a single control command. The Lovato 11B115400110 is particularly suited to AC-1 applications involving resistive or slightly inductive loads, including heating systems, lighting banks and power distribution circuits.
Its AC/DC coil supports integration with different control supply arrangements, while the four-pole configuration provides additional switching flexibility compared with a standard three-pole contactor. Auxiliary contacts, interlocks and other compatible accessories can be selected separately to suit the control system.
