Circuit Breakers

Circuit breakers are a type of electrical device designed to protect circuits from sudden overloads of current. Circuit breakers work by interrupting the flow of electricity after a short circuit or an overload occurs on the line. This interruption allows the circuit to be reset, and the circuit breaker can be used to protect both electrical and electronic components from damage due to overloads or power surges.

219-4-33292-4 Application Field and Working Principle

The 219-4-33292-4 is a type of circuit breaker specifically designed for commercial and industrial applications. This circuit breaker is rated for a full-load current of 4000A, and it has a short-circuit rating of 25kA. It is UL listed and CSA certified, and it is designed with features such as current limiting, a trip indication, and a temperature switch.

The 219-4-33292-4 circuit breaker works by monitoring the current in a circuit and trips (opens) when the current exceeds the designated threshold. When this occurs, the breaker will trip and interrupt the circuit, preventing the current from continuing to flow and causing damage. This trip mechanism is controlled by several sensing elements, such as a thermal magnetic switch, a current transformer, and an overload indicator.

The thermal magnetic switch is designed to sense when the current exceeds the designated maximum by monitoring the temperature of the circuit. When this happens, the switch trips and the breaker opens, interrupting the circuit and preventing further damage. The current transformer is designed to measure the current in the circuit, and the overload indicator is designed to alert the operator of an overload so that it can be reset.

The combination of these components ensures that the 219-4-33292-4 circuit breaker can protect circuits from damage caused by overloads, power surges, and short circuits. This makes it ideal for use in applications such as manufacturing facilities, large buildings, and electronic equipment.

In summary, the 219-4-33292-4 circuit breaker is an highly reliable and efficient circuit breaker specifically designed for commercial and industrial applications. It features a full load current rating of 4000A and a short-circuit rating of 25kA, and it utilizes a combination of sensing components to ensure that the circuit is protected from overloads, power surges, and short circuits. This makes it an ideal choice for a wide range of applications.
