11B115400220 – 4P CONTACTOR B115.4.00 220/240
Lovato 11B115400220 is a B115 four-pole power contactor with four normally open contacts, a 160 A AC-1 rating and a 220–240 V AC/DC control coil for high-current industrial switching.
Why Choose the Lovato 11B115400220 Four-Pole Contactor?
The Lovato 11B115400220 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 11B115400220 features an AC/DC coil rated from 220–240 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.

Reliable Four-Pole Industrial Power Switching
Four-pole contactors enable several conductors or circuits to be switched simultaneously from a single control command. The Lovato 11B115400220 is particularly suited to AC-1 applications involving resistive or slightly inductive loads, including heating systems, lighting banks and power distribution circuits.
Its 220–240 V AC/DC coil supports integration with common industrial control supplies, 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.
Typical Applications
- Industrial heating and resistive load control.
- Lighting banks and commercial lighting systems.
- Power distribution and switching assemblies.
- HVAC and building-services equipment.
- Industrial machinery and process equipment.
- Electrical control panels and automation systems.
