Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

In modern electrical terms, the designation CEG1-34586-9-V identifies a particular type of circuit breaker. This specific model, manufactured by the CHANGHONG Industrial Group Co. Ltd., is designed for use in various types of industrial and residential installations, depending on the requirements of the project.

The CEG1-34586-9-V circuit breaker is a three-pole, double-curve, electronic short-circuit trip mounted circuit breaker, with a nominal current rating of 70A, in a fixed-mounted version (3-phase) 75A, and a variable-mounted version (3-phase) up to 100A. This model is suitable for AC voltage of 415V to 440V, AC frequency 50/60Hz, and a commissioning distance of ≤25mm. It features six adjustable parameters (time delay di/dt and short-circuit protection), and is designed to conform to IEC60947-2 standard for operation in various regions and use cases.

The working principle of the CEG1-34586-9-V circuit breaker can be summarised into three main steps. In the first step, the main contacts of the circuit breaker are closed, allowing current to flow through the circuit. In the second step, if the current exceeds the nominal value, a thermal and/or magnetic device is triggered. The third step involves the electrical contacts of the breaker opening, breaking the current flow and thus protecting the circuit.

The CEG1-34586-9-V circuit breaker is designed for a variety of applications, including motor circuits, air conditioning systems, commercial and household electrical circuits, and hazardous area protection. In addition to the standard range, additional accessories and specialized versions are available for specific use cases.

In conclusion, the CEG1-34586-9-V circuit breaker is a versatile and reliable device designed for a variety of applications and environments. The triple-pole, double-curve design ensures sufficient current interruption for all requirements, while the adjustable parameters allow for precise optimization for any specific use case. Furthermore, the IEC60947-2 standard ensures reliability and compatibility in almost any region and installation.
