Circuit breakers are important devices that protect equipment from electrical damage due to overloads or short circuits. APL 11-28127-1 is a type of circuit breaker that offers surge protection and current monitoring. This article will discuss the application field and working principle of APL 11-28127-1.

Application field of APL 11-28127-1 circuit breaker primarily includes industrial, commercial and residential applications. Its task is to protect electrical circuits and equipment from over-voltages and over-loads. It can be applied in various environmental conditions and in areas requiring circuit protection. Additionally, it can be used to provide surge protection to sensitive electronic equipment, such as medical equipment, communication systems and electrical instruments. The APL 11-28127-1 circuit breaker is also suitable for use in motor control centers, step-down transformers, trains, ships, aircraft and other safety-critical applications.

The working principle of APL 11-28127-1 circuit breaker is similar to other types of circuit breakers. It uses an electromagnet to detect surges and overloads in the connected circuit. When a surge or overload is detected, the electromagnet will open the circuit breaker, and then the contact will be opened to prevent the current from passing.

The electromagnet of the APL 11-28127-1 circuit breaker can detect over-currents, over-voltages and over-loads. The current-monitoring devices inside the circuit breaker performs periodic tests in order to detect surges, over-loads and shorts. When such a fault is detected, the contact will be opened, thus preventing electrical damage. Additionally, the circuit breaker also has a thermal contact that will open the contact if the temperature of the device reaches high levels.

In addition to the current-monitoring capabilities, the APL 11-28127-1 circuit breaker also has several other features. The device has an adjustable current-settings dial that can be used to set the maximum allowable current in the circuit. It also includes a manual reset switch that allows the Breaker to be easily reset after an overload has been detected. Finally, its construction features an isolation switch to ensure that the Breaker is completely isolated from the connected circuit.

In conclusion, the APL 11-28127-1 circuit breaker is a type of circuit breaker that offers surge protection and current monitoring. Its application field includes industrial, commercial and residential applications. Its working principle involves the use of an electromagnet to detect surges, overloads and short circuits. Additionally, the device includes several features, such as an adjustable current-settings dial, a manual reset switch and an isolation switch. These features ensure that the circuit breaker provides optimal protection against power surges and other electrical faults.
