4430.1129

Circuit Breakers are essential components of any electrical system. They are used to ensure the safe operation of the system, by protecting it from short circuits, overloads and ground faults. The 4430.1129 is a type of circuit breaker that is designed to provide reliable protection for demanding electrical applications.

Application Fields

The 4430.1129 circuit breaker is specifically designed for the protection of medium voltage systems, such as motors, transformers and switchgear. It is also suitable for generator protection and may be used to protect sensitive loads such as computers, control systems and communications equipment. This type of breaker is also suitable for use in hazardous locations, as it meets the relevant safety standards.

Working Principle

The 4430.1129 is an air-magnetic circuit breaker, which means that it uses compressed air to interrupt an electrical current. When an over-current occurs, the breaker will interrupt the circuit by breaking open a pair of contacts. This is done by compressing a sealed, magnetic force that is created by an electromagnet. Once the current is interrupted, a spring will restore the contacts back to their original positions and the breaker will reset.

The 4430.1129 is a reliable circuit breaker, due to its robust construction and advanced design features. It features fast response times, making it suitable for both high and low-voltage applications. It is also designed to be flexible, allowing users to customize the settings and reset time of the breaker. This means that the breaker can be set to protect the system efficiently and effectively.

The 4430.1129 circuit breaker is an important component of any electrical system, ensuring safety and reliability. It is suitable for a wide range of applications and offers excellent protection against overloads, short circuits and ground faults. Its advanced design features also allow it to be customized to meet different requirements, making it a versatile and reliable choice for any project.
