The Contactors are the result of an in-depth analysis of customer requirements. Optimizing the mechanical, electrical and aesthetic design was key to producing the A-Line system concept that provides a new generation of coordinated, close-coupled low voltage products.
Contactors are coordinated with the ABB molded case circuit breakers, disconnect switches and overload relays Provides designers, panel builders and end users with the best performance, reliability and flexibility. Pre-assembled connections bar kits allow the close-coupling of ABB components to save space, assembly material, installation time and minimizes cabling.The new design of the large A-line contactors, places the magnet at the top of the unit and the main contact system at the bottom. This design provides a number of advantages over previous designs:Easy connection between the contactor and other system components because the terminals are at the same level.

Motor contactors are relays with large current capacity for connecting and disconnecting motors from power supplies. Most motor contractors are multi-pole devices in order to control all of the current-carrying conductors. Typically, motor contactors are set to a predetermined load value. When the maximum load value is crossed, the overload protection device opens the motor starter control circuit and turns off the motor. For best results, motor contactors should be durable, high-quality, long-lasting devices.
All connections to the control circuits are easily accessible from the front which facilitates installation and measurement.
Not necessary to remove power cables for inspection and maintenance.
Electrical operation of the contactor is impossible during contact inspection since the magnet system is removed with the front section.
Low, built-in terminals and the option of terminal shrouds give you a touch-safe solution.
