Motor protection and control

To keep it running, you need Control

ABB’s motor protection and control offering is among the widest on the market. From system integrator, OEM, engineering consultant and distributor to panel builder and industrial end-user, our comprehensive range of motor starting solutions, products and services delivers the certainty of consistent quality and performance.

3-pole contactors and overload relays for motor starting and power switching
To make the most, you need control

ABB 3-pole contactors offer an exhaustive selection of products for simple and extreme applications 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, spring and ring tongue through our ranges. So whatever your need of a contactor might be, ABB will have a variant meeting just that.

Manual motor starters

A complete motor protection concept

Manual motor starters are electromechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and to provide fuse less protection against short-circuit, overload and phase failures. Fuse less protection saves costs, space and ensures a quick reaction under short-circuit condition by switching off the motor within milliseconds. Starter combinations are setup together with contactors.
