Contactors are electromagnetically operated switches that are used to make or break the connection between the load and power supply. This happens when the control power flowers through the magnet coil of a contactor that creates a magnetic field by attracting the mechanical contact carrier. The mechanical contact carrier returns to the starting position once interrupted by the coil control circuit.
To keep things running you need control!
ABB contactors are provided in either three or four power pole configurations with a variety of accessories, including auxiliary contacts, easy connecting links (between products), interlocks, and bus bars. These devices are used for controlling switching power circuits, single and three-phase motors.
The ABB contactors belong to the class of air-break contactors. On removal of coil power, an arc will be created due to the contacts opening. These contactors extinguish the arc by separating the contacts with enough distance.
Contactors are approved according to IEC / EN 60947-4-1, IEC / EN 60947-5-1., and Contactor relays are approved according to IEC / EN 60947-5-1.
ABB Contactor Range
The ABB comprehensive selection of contactors is used for simple and extreme applications and also with purpose-specific products. The AF contactor technology has revolutionized the use of contactors around the globe with different network conditions.
In addition, a mini-contactor range also available for specific connection possibilities along with compact dimensions. The efficient AS contactors allow in optimizing the equipment design.
ABB ranges include terminals between screw, push-in spring and ring tongue.
Basically, whatever your need for a contactor is, with the ABB product range, you’ll always find a fix.
