Circuit Breakers

APL2-7571-8 application field and working principle

Circuit breakers are devices designed to protect electrical systems from overloads, short circuits or other potential hazards. The APL2-7571-8 circuit breaker is a type of miniaturized circuit breaker, specifically designed for residential applications. It features a compact, lightweight design, and is able to provide reliable overload protection up to a voltage of 480V.

Application Field

TheAPL2-7571-8 circuit breaker is designed for residential use and is applicable in Class CC, Qob and Qcd safety switches, as well as other types of industrial and commercial applications. It has an operating temperature range of 0 °C to 70 °C, makingit suitable for indoor and outdoor uses. It is also UL listed and meets the requirements of the National Electrical Code (NEC). As such, it is an ideal choice for residential, industrial and commercial applications.

Working Principle

The APL2-7571-8 circuit breaker features a trip-free mechanism and thermal-magnetic protection technology. The trip-free mechanism ensures that even after the circuit breaker has been activated, it cannot be deactivated manually. This helps to ensure that all electrical systems are protected against overloads or short circuits. The thermal-magnetic protection technology uses a combination of thermal and magnetic elements to detect overloads. When an overload is detected, the circuit breaks automatically, even before the fuse blows.

The APL2-7571-8 circuit breaker also features an adjustable trip setting, allowing users to customize the trip settings according to their needs. The adjustable trip setting can be used to increase or decrease the sensitivity of the trip-free mechanism, providing further protection against potential hazards. In addition, it also has a reset button, allowing users to reset the circuit breaker manually in case of an overload or short circuit.

Conclusion

The APL2-7571-8 circuit breaker is a small, lightweight and highly reliable circuit breaker designed for residential applications. It is UL listed and meets the requirements of the NEC, making it an ideal choice for indoor or outdoor residential use. The trip-free mechanism and adjustable trip setting provide an extra layer of protection from potential hazards, while the reset button ensures that the device can be manually reset if needed.
