Circuit breakers are essential components of any electrical or electronic system. Their primary purpose is to provide protection by interrupting the flow of electricity in the event of an overload or short circuit. The 914280 model of circuit breaker is designed to provide reliable and robust protection for sensitive systems, such as those found in telecommunications and data networks. This article will discuss the application field and working principle of the 914280 circuit breaker.

The 914280 circuit breaker is designed to be used in applications where standard circuit breakers would not provide sufficient protection. This includes installation in distributed power systems, such as solar and wind-powered installations, and where arc flash protection is required. The 914280 is also suitable for high performance audio applications, where it can provide precision current monitoring and protection.

The 914280 circuit breaker is composed of two main parts, the contact and the terminal block. The contact is a metal strip that is connected to the terminal block via a pin. When the electrical current exceeds the pre-defined limit, the pin will move, opening the contact and interrupting the flow of electricity. The main advantage of the 914280 is that it is designed to respond quickly to protect sensitive systems. This is in contrast to standard circuit breakers, which are designed to respond slower, thus allowing more time for a fault to develop.

The contact of the 914280 is normally closed, meaning that when there is no current, no power is transmitted, so that the circuit will still remain safe. However, when the power is exceeded, the contact will move, and the current will be interrupted. This process is known as \'tripping\' the circuit breaker, and it provides a powerful mechanism for protection against over-currents, short-circuits, and arc flashes.

The 914280 circuit breaker is also equipped with a built-in thermal-magnetic apparatus. This is necessary to protect against excessive temperatures, which can lead to circuit breaker failure. The thermal-magnetic apparatus monitors the temperature of the contact and will trip the circuit breaker if the temperature exceeds a specific pre-defined limit. In addition, the thermal-magnetic apparatus can also be used to detect the presence of an arc flash, providing a further layer of safety.

The 914280 circuit breaker is designed to provide reliable and robust protection against over-currents, short-circuits, and arc flashes. By providing a quick and effective response, the circuit breaker is able to provide assurance that a fault will not have time to cause significant damage to the system or components. The additional thermal-magnetic apparatus provides additional protection against excessive temperatures, ensuring that the circuit breaker can provide powerful yet reliable protection.
