Introduction

Electromechanical contactors are considered a key component in the industrial automation and power control technology. The CC225/4SA500 contactors are the most commonly used contactors for industrial applications. This article explores the application field and working principle of the CC225/4SA500 contactors, and explains why these contactors are used in commercial and industrial applications.

Application Field and Utility

The CC225/4SA500 contactors are designed to be used in many commercial and industrial applications. They are often used in motor control circuits, as well as for relays and switch circuits. The CC225/4SA500 contactors are designed for switching AC and DC voltage, and offer a wide range of current ratings. These contactors are also suitable for most motor types – including AC motors, DC motors, servo motors, and brushless DC motors.In addition to motor control, the CC225/4SA500 contactors can also be used in temperature and process control circuits. Moreover, these contactors are suitable for over-current protection systems and for switching high-capacity loads. The contactors are designed for use in harsh industrial environments and can operate reliably in temperatures ranging from -25°C to +60°C.

Basic Features and Specifications

The CC225/4SA500 contactors offer a wide range of features and specifications. These contactors are designed with a 200A/400A power contact rating, and can be ordered with AC and/or DC coils. The contactors are also equipped with a bimetallic safety switch, which detects any overheating of the contactor and quickly cuts off current to the contactor. The contactors are also designed with a thermal overload protection feature, which is designed to protect the contactor from damaging overloads.Moreover, the contactors feature an electromagnetic static hold-in mechanism which ensures the contactors remain closed even in the event of a power failure. The contactors are designed to be impact resistant, and have a creepage distance of 6mm and an insulation voltage of 690V. The contactors also have a dielectric strength of 4kV and an impulse withstand voltage of 5kV.

Working Principle

The working principle of CC225/4SA500 contactors is based on the use of electromagnetic coils. These contactors are designed with an AC or DC coil which, when triggered by an electric signal, creates an electromagnetic force. This electromagnetic force causes the contactors’ movable contacts to move in a closing or opening direction. When the movable contacts are closed, the contactors are switched on and a current flows through the circuit. When the movable contacts are open, the contactors are switched off and there is no current flow.

Conclusion

The CC225/4SA500 contactors are widely used in commercial and industrial applications. These contactors are powerful and reliable, offering a wide range of features and specifications. The contactors are designed for switching AC or DC voltage, have a wide range of current ratings, and can be used in motor control circuits, as well as in temperature and process control circuits. The contactors also offer an electromagnetic static hold-in mechanism and a bimetallic safety switch, which provide additional safety and protection.
