APL111-1REC4-2920-52 Circuit Protection

Circuit Breakers

Circuit breakers are devices used in an electrical system to protect against overloads or short circuits. They detect any abnormality in the flow of electricity, and then disconnect the circuit when it is not safe. The APL111-1REC4-2920-52 is an example of a circuit breaker designed to provide flexible protection for a variety of applications.

Applications

The APL111-1REC4-2920-52 is designed for use in residential, commercial, and industrial applications. It can be used to protect single-phase circuits, as well as three-phase circuits. It is suitable for a variety of applications, including motor protection, lighting circuits, and air conditioning systems. The breaker can also be used in grids with different voltage levels, ranging from 110V to 440V.

Working Principle

The working principle behind the APL111-1REC4-2920-52 circuit breaker is based on the thermal-magnetic effect. When an overload or short circuit occurs, the temperature of the breaker rises, which causes an increase in the magnetic field of the breaker. This increases the force on the breaker, which causes it to trip and disconnect the circuit. This helps to prevent any further damage to the electrical system.

Advantages

The APL111-1REC4-2920-52 circuit breaker has several advantages over other types of circuit breakers. It is very reliable and easy to install, and its operation is completely automated. It does not require manual resetting after it trips, and its operation is instantaneous. The breaker also has a long life span and is extremely durable, making it a cost-effective solution for most applications.
