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.

Main benefits

• Harmonized main accessory range (auxiliary contacts, signal contacts, shunt trips and undervoltage releases) for MS1xx and MO1xx family
• Compact design
• Efficient planning and installation perfectly matching the ABB contactor family
• Simple connecting links ensure electrical and mechanical connection to build direct-on-line starters
• Less machine downtime by protecting motors and reduced trouble shooting 
• Reduction of maintenance expenditures by protecting motors

Main features

• Manual control / short-circuit current and overload protection
• Adjustable current setting for overload protection and magnetic trip indication
• Disconnection function
• Temperature compensation
• Remote control via undervoltage release or shunt trip
• Short-circuit service breaking capacity Ics up to 100 kA.
