4404.0001 Circuit Breakers - Application Field and Working Principle

Circuit breakers are designed for a wide range of residential and commercial applications. They are typically installed in homes, factories, office buildings, and other places where electricity is required. Circuit breakers are key components in any electrical system, as they help protect against damage to electrical devices, systems, and people. They are also essential in preventing potential fires caused by over-heating or over-current.The 4404.0001 circuit breaker is a three-pole molded case circuit breaker. It features a trip-free feature, manual switch-off, and drawout construction. It has a current rating of up to 4500 A and comes in both bolted and pluggable versions. 4404.0001 is designed for quick connect/disconnect of the circuit breaker at the control panel.A circuit breaker is designed in two distinct parts – the operating mechanism and the arc extinguishing chamber. The operating mechanism is comprised of a spring or an electromechanical solenoid, which is used to initiate the opening or disconnecting of a circuit. The operating mechanism is also used to control the timing of the circuit breaker’s operation. The arc extinguishing chamber is comprised of metal divides, which are used to create an arc-free environment. The metal divides also allow for the draining of the arc quenching energy when the circuit breaker trips.The 4404.0001 circuit breaker has a trip-free feature, meaning that the device will remain tripped in the event of an over-current or short-circuit. If an over-current condition occurs, the voltage will increase, triggering the device’s operating mechanism to automatically disconnect the circuit. The operating mechanism will then remain tripped until the short-circuit or over-current condition is remedied.The manual switch-off feature allows for manual resetting of the circuit breaker, in the event of an over-current or short-circuit. The manual switch-off button is found on the side of the breaker and must actively be pushed in order to reset the breaker. When the manual switch-off button is pressed, the voltage will decrease, deactivating the operating mechanism and allowing the breaker’s connection to be restored.In addition to its manual switch-off feature, the 4404.0001 circuit breaker also offers drawout construction. This feature allows the breaker to be removed from its enclosure without the need to de-energize the power on that circuit. The contact pins of the breaker can also be replaced within the drawout construction, allowing for shorter downtime in the event of a defective component.The 4404.0001 is a reliable, robust circuit breaker that can be used in a wide range of applications, both residential and commercial. Its trip-free feature, manual switch-off, and drawout construction make it ideal for protecting against fires, and for easy switching and maintenance.
