Circuit breakers are one of the important pieces of equipment used in electric power transmission and distribution. They provide automatic protection against overloaded circuits and short circuits. The 219-4-5055-1 circuit breaker is a popular type of circuit breaker with a wide application field and various working principles.

The type of 219-4-5055-1 circuit breaker is a two-pole circuit breaker, suitable for AC 50/60Hz, rated voltage up to 220V, rated current up to 16A. This type of circuit breaker is widely used in household electrical appliances, office area wiring, power protection and other fields.

The design of the 219-4-5055-1 circuit breaker is based on an age-old and proven principle. Its internal structure consists of a bimetallic thermal switch, a switch lever, a settable voltage, a fixed contact, a moving contact and an arc extinguishing chamber.

In normal circumstances, the moving contact and fixed contact of the 219-4-5055-1 circuit breaker are connected, so that the current can flow through them. When the current exceeds the rated current value, the bimetallic thermal switch will heat up and move. This movement will be passed through to the switch lever, and the switch lever will move and separate the moving contact from the fixed contact, interrupting the circuit, thus protecting the circuit from overload or short-circuit.

When the current goes through the arc extinguishing chamber between the moving contact and the fixed contact, an arc is generated. The arc will be automatically extinguished when it reaches the peak point of the arc voltage to prevent the contact from burning due to the arc.

The operation of the 219-4-5055-1 circuit breaker is smooth and reliable, making it suitable for use in a variety of applications. Its wide application field includes control circuits of motor starters, household appliances, illumination, electric stove and other electric equipment. Its excellent features make it a preferred choice among electrical engineers.

In conclusion, the 219-4-5055-1 circuit breaker is a popular type of circuit breaker with its wide application field and reliable working principle. It has become a popular choice among electrical engineers due to its excellent features and reliable operation.
