Circuit breakers are an essential piece of safety and protection equipment used in all types of electrical systems. A circuit breaker is a device that interrupts the flow of electricity by interrupting the circuit. The 4404.0105 is one type of circuit breaker, which is specifically designed for high surge, high short-circuit current applications in medium-voltage systems.

4404.0105 is designed with a top-mounted gas-discharge surge arrester, which when combined with advanced trip circuitry and self-test capabilities, and can better protect a system from surge-related incidents. The breaker is rated to carry a maximum current of 1,000 amps and operate up to a voltage of 69 kV.

The 4404.0105 differs in several ways from other breakers. It has been designed to include a rapid response time, meaning it will trip before dangerous levels of current or voltage can be transmitted. It also has improved arc-quenching, which ensures optimal level of protection from surge and high overload currents.

The 4404.0105 circuit breaker works by interrupting the circuit when an overvoltage or overcurrent is detected. When the breaker senses the overcurrent or the overvoltage, the internal magnetic field generated by a permanent magnet on the breaker’s housing causes the contacts to close and thereby shut off the circuit. The operating time of the breaker is relatively short, making it ideal for applications that require fast response time and reliable protection.

The 4404.0105 also has several built-in features, such as self-testing, which allows the breaker to test itself to ensure it is still providing optimal protection. It also includes a high-voltage protection feature, which automatically shuts off the circuit if the detected voltage exceeds a predetermined level. The breaker is also able to monitor the system voltage, allowing the user to always be aware of the system’s current status. Finally, the top-mounted arrester provides an additional layer of protection against surge-related incidents.

In summary, the 4404.0105 circuit breaker is designed to provide reliable and rapid response protection in high surge, short-circuit current applications in medium-voltage systems. It features a top-mounted gas-discharge surge arrester, advanced trip circuitry, and self-test capabilities, providing a high degree of protection against surges and high overload currents. The breaker is also able to detect overvoltage and overcurrents, and the self-tests ensure the breaker’s performance. The 4404.0105 provides reliable protection, ensuring that the system is always safe and secure.
