4430.1274 Circuit Protection

Circuit breakers are electrical safety devices used to protect sensitive electronic equipment from damage caused by power surges, short circuits, and over current. The 4430.1274 circuit breaker is used primarily in industrial and commercial applications. It is a highly reliable and cost-effective solution, providing protection by automatically disconnecting the power in the event of a fault or overload.

The 4430.1274 circuit breaker is designed with an adjustable trip point, which can be set according to the load current rating. This allows the user to select the protection level required for their application, while also offering the flexibility to accommodate differences in the electrical environment. The circuit breaker is equipped with a manual reset button, which can be used to reset the breaker in the event of an over current condition. In addition, the circuit breaker can also be manually reset via a remote switch.

The 4430.1274 circuit breaker is designed to meet the safety requirements of UL 489 and IEC 60950-1. It has been tested to withstand shocks and vibrations, as well as electromagnetic interference. The circuit breaker is certified for use in hazardous locations, such as those in oil, gas and petrochemical industries.

The working principle of the 4430.1274 circuit breaker is based on the principle of thermal-magnetic tripping. When the load current exceeds the set limit, the thermal devices within the circuit breaker heat up and create a magnetic field, which trips the mechanism and cuts off the power supply. This type of breaker is designed to provide reliable protection in the event of a short circuit, overvoltage, or overload condition.

The 4430.1274 circuit breaker is widely used in commercial, industrial, and residential applications. It is a reliable and cost-effective solution for protecting sensitive electronic equipment from power surges, short circuits, and over current. The adjustable trip point allows for the protection level to be adjusted according to the load current rating, while the manual reset button allows for manual resetting in the event of an over current condition. The thermal-magnetic tripping mechanism ensures reliable protection from short circuit, overvoltage, or overload conditions.
