Introduction to 219-3-7268-143 Circuit Breakers

Circuit breakers are essential components in any electrical system and their primary function is to protect against excessive current, providing both overload protection and short-circuit protection. The 219-3-7268-143 circuit breaker is a particularly useful type of 3-pole specter breaker which is used primarily to replace discontinued breakers in old switchboards. This article will outline the application fields and general working principle of 219-3-7268-143 circuit breakers.

Application Fields of 219-3-7268-143 Circuit Breakers

The 219-3-7268-143 circuit breaker is widely used in a variety of applications where 3-pole circuit breakers are required. These include residential and commercial properties, and industrial applications where the presence of a quick-make and quick-trip breaker is necessary for equipment safety. This type of circuit breaker is particularly useful for residential applications where the circuits are subject to frequent overload due to the presence of multiple items such as heaters, dryers and KitchenAid machines all on the same circuit.

Working Principle of 219-3-7268-143 Circuit Breakers

The 219-3-7268-143 circuit breaker utilizes both electromechanical and electronic components to provide its quick-make and quick-trip capabilities. When an overload current is detected, an electromechanical bimetal element is instantly triggered, providing the breaker with a quick trip capability. The bimetal element is then able to separate the two poles of the breaker, thus preventing further current from being conducted. The on-board microprocessor and electronic components ensure that the breaker will trip within a few milliseconds of detecting an overload current.The 219-3-7268-143 circuit breaker also has a special positive pole controller (PPC) which is able to detect the presence of a short circuit in any of the breaker poles. If a short circuit is detected, the breaker will trip and open the current flow, thus preventing the circuit from being overloaded. The PPC also includes a low-level circuit to prevent the breaker from operating for too long during an overload condition
