Contactors and contactor relays

To keep things running you need control

ABB offers a comprehensive selection of contactors for simple and extreme application as well as products with specific purposes. The AF contactor technology revolutionizes how we use contactors and allows use in all parts of the world and in all network conditions. Furthermore, mini-contactor range offers compact dimensions and specific connection possibilities. The AS contactor is efficient and allows you to optimize your equipment design. You can choose terminals between screw, push-in spring and ring tongue through our ranges. So whatever your need of a contactor might be, ABB will have a variant meeting just that.

Installation contactors

Modular DIN rail components

ABB’s hum-free installation contactor designs offer a wide range of ratings from 16 A to 100 A. Widely used in buildings for switching and controlling lighting, heating, ventilation, motor and pumps, the installation contactors take noise reduction to a new level. With an innovative AC/DC design that eliminates hum, a selection of tool-free accessories as well as manual and automatic versions, installation contactors offer peace of mind in noise-sensitive applications.
