Contactors (Electromechanical)

A contactor is an electro-mechanical switching device used to break an electrical circuit in order to either interrupt the flow of electric current or to prevent its flow.

The CC75LD12 is a contactor and is part of the products in ABB\'s contactor range. It is a three-phase contactor suitable for actuating AC motors. It is designed for direct or remote control of motors, resistive loads, transformers, and capacitors. It is rated up to 7.5 kW (400V) or 11kW (440V) at 400 Hz.

Application Field

The CC75LD12 contactor is a three-phase contactor suitable for actuating AC motors. It is most frequently used in industrial or commercial settings for controlling and monitoring electrical systems.

The CC75LD12 contactor can be used for switching inductive and capacitive loads such as transformers and capacitors. It can also be used to control resistive loads, as well as for controlling and monitoring motors and other devices.

The CC75LD12 is also suitable for use in hazardous areas, and is certified according to UL and CSA standards. It offers motor protection and can be used with a variety of accessories, including overload relays and contactor disconnect switches.

Working Principle

The CC75LD12 contactor works by controlling the flow of electricity to a motor or to a circuit. When the contactor is engaged, electricity flows through the contactor and when it is diseng aged, the flow of electricity is interrupted.

The operating coil of the contactor is the part that receives the current and serves to attract the armature and open the contact points. When the contactor is turned off, the coil releases the armature and the two contact points disengage, thus interrupting the flow of electric current.

The contactors have two main components: a contactor and a coil. The contactors themselves are composed of a metallic contact and a moving armature, which is used to open and close the contacts. The coil is used to attract the armature and open the contact points. The CC75LD12 contactors have two or three contact points.

The CC75LD12 contactor is available in a variety of models suitable for different amperages and voltages, and can be used for a wide range of applications. The contactor is UL and CSA certified for applications in hazardous areas, and is suitable for motor protection applications.
