Introduction

A contactor is an electrically operated device which mechanically switches either AC or DC power. Contactors typically consist of a metal housing containing one or more moving contact points that serve as electrical and mechanical connection points. Contactors are a type of motor-driven, electromechanical switches that are used to switch electrical circuits. They are commonly used to control motors, lighting, and heating and are ideal for industrial applications where large amounts of power must be switched on and off quickly. The contactor CC75SA120 is a three-pole, size S02, single-phase reversing contactor.

Application Field

The CC75SA120 contactor can control a variety of electrical loads, including resistive loads (heaters, lamps, etc.), inductive loads (motors and transformers), and capacitive loads (capacitors). It is used for controlling motors, power transmission, and automatic control systems. The CC75SA120 provides control of single-phase AC power for applications such as heating, air conditioning, refrigeration, and lighting control. It also finds use in more advanced applications such as machine tools, elevators, and packaging machines.

Working Principle

The contactor CC75SA120 works by energizing a coil that moves a series of contact points on a switch between open and closed positions. When the coil is energized, a movable metal bridge is magnetically pulled towards the electromagnet and it closes the contacts. This allows electricity to flow from the source to the load. Then, when the coil is de-energized, the movable bridge is pulled away from the electromagnet, opening the contacts and stopping the flow of electricity. This process is repeated when the coil is energized, allowing the contactor to be used as an on-off switch for the load.

The contactor CC75SA120 provides effective control over single-phase AC loads while ensuring reliable operation. Its robust design provides a high degree of protection to motor, fan and other load components. The contactor is designed for simple field wiring and easy access to maintenance features, providing reliable performance for a wide variety of applications.
