Across the Line ABB Contactors
The ABB A-line contactor range has the same design from 9A to 1050A (AC3 duty) motor loads and is developed for a broad range of DC and other AC applications. This makes it easier to match your needs with fewer components.
This product has benefited of the latest research in electrical design and component layout incorporating the most recent developments in safety aspects, materials and electronics.
This range offers a total system concept. The A-Line together with ABB's fuse, fuse less short circuit protections, and electronic overload relays provide the basis for a new generation of apparatus designed to an ABB-Line system community. Our focus is to provide designers, engineers, installers and end users with the best possible system solutions.

ABB Thermal Overload Relays
ABB Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in the event of overload or phase failure. Starter combinations are setup together with block contactors and mini contactors.
The thermal overload relays are three pole relays with bimetal tripping elements. The motor current flows through the bimetal tripping elements and heats them directly and indirectly. In case of an overload (over current), the bimetal elements bent as a result of the heating. This leads to a release of the relay and a change of the contacts switching position (95-96 / 97-98).

Example of application
Being easy to use like a thermal overload relay and compatible with standard motor applications, an electronic overload relay is convincing, above all, due to its broad setting range and low power consumption. The overload relays are connected directly to the contactors.
