219-4-21341-5

Circuit Breakers are important safety devices in any electrical system. They are responsible for preventing electrical damage or overloads caused by shorts, open circuits, or excessive currents. The 219-4-21341-5 circuit breaker is designed to provide protection against over-currents, short circuits, and ground-fault conditions.

Application Field

The 219-4-21341-5 circuit breaker is commonly used to protect electrical systems found in industrial applications, residential dwellings, and other commercial buildings. It is also often used in high-power applications, such as in adjustable speed drives and motor control centers. The 219-4-21341-5 circuit breaker is also suitable for use in hazardous locations, such as oil and gas installations.

Working Principle

The 219-4-21341-5 circuit breaker consists of a molded-case switch and a device to detect, limit, and clear over-current conditions. When the current level reaches a predetermined threshold, the molded-case switch will automatically open the circuit, which will cause all electrical current flowing through the circuit to stop immediately.

The circuit breaker also has a built-in device to detect and limit ground-faults. A ground-fault is an arrangement of currents which cause an imbalance of electrical potential. If the ground-fault current grows to a sufficient level, the breaker will trip and open the circuit preventing damage to the electrical system.

In addition, the 219-4-21341-5 circuit breaker has a built-in thermal protection feature. This feature monitors the temperature of the circuit breaker and will trip in the event that the circuit breaker overheats. This is important to prevent the circuit breaker from becoming damaged or causing a fire.

The 219-4-21341-5 circuit breaker is a reliable over-current protective device. It is capable of detecting and isolating any dangerous situations quickly and effectively, making it an excellent choice for industrial and commercial applications.
