Circuit breakers are essential components in any electrical system. The 4420.0232 is a standard circuit breaker with several unique features, making it the perfect choice for many applications. This article will explain the applications and working principles of the 4420.0232 circuit breaker.

Overview

The 4420.0232 is a miniature two-pole circuit breaker. It has a breaking capacity of 10,000 A and a rated voltage of up to 380 V. It provides excellent protection from short circuits, over-currents, and overloads. It is suitable for existing AC and DC systems, as it can be used in single or three-phase systems. It is also designed to fit within standard mini-breaker enclosures.

Application

The 4420.0232 is the perfect choice for a wide range of applications. It is ideal for residential, commercial and industrial applications, such as household appliances, data centers, manufacturing plants, and office spaces. It is also suitable for use in power distribution systems, as well as in motor control systems. Additionally, the circuit breaker is suitable for generator protection in control and motor control systems.

Working Principle

The 4420.0232 features a thermal-magnetic trip mechanism, which helps to protect electrical systems from faults. This trip mechanism uses a temperature-sensitive element to detect any increase in temperature above a pre-determined threshold. Once the temperature threshold is exceeded, the element triggers an insulation fault breaker, tripping the circuit breaker and disconnecting the electrical supply. This helps to protect against overloads and short circuits.

The 4420.0232 also features a combined thermal-magnetic trip mechanism, which combines the functions of both a thermal and a magnetic trip mechanism. This mechanism helps to provide precisely timed trip operation, making it suitable for protecting against overloads and short circuit protection. Additionally, the trip mechanism helps reduce the incidence of nuisance tripping, making it suitable for motor control applications.

Conclusion

The 4420.0232 is a miniature two-pole circuit breaker with a breaking capacity of 10,000 A and a rated voltage of up to 380 V. It offers excellent protection from short circuits, over-currents, and overloads, making it suitable for a wide range of applications. It features a thermal-magnetic trip mechanism and a combined thermal-magnetic trip mechanism, providing precise trip operation and reducing the incidence of nuisance tripping.
