APL111-1691-1 Circuit Protection

Circuit Breakers are commonly used pieces of safety equipment that protect exposed electrical circuits from damage due to overloads or short-circuits. A circuit breaker is an important part of an electrical system and is designed to provide protection against electric shock, fire, and other hazards associated with the improper use of electricity. The APL111-1691-1 Circuit Breaker is a type of circuit breaker which utilizes an adjustable current limiting device to protect electrical circuits.

APL111-1691-1 Application Field and Working Principle

The APL111-1691-1 Circuit Breaker is a microprocessor-controlled, adjustable over-current protection device that employs the principles of current limiting in order to protect electrical systems from damage due to excessive current. It is designed to prevent overloading of an electrical system and protect electrical components from damage caused by short-circuits. It can be used in both single-phase and multi-phase electrical systems.

The APL111-1691-1 Circuit Breaker features adjustable current limiting thresholds. This allows the user to set the threshold at a level that is suitable for the particular application. The adjustable current limiting device is composed of several components, including a current transformer, a power reference circuit and a current & voltage detector. The power reference circuit acts as a reference voltage that is compared with the input voltage. When the current reaches the adjustable threshold, the current & voltage detector activates the power reference circuit and sends a signal to the microprocessor, which then trips the circuit breaker.

The adjustable current limiting feature of the APL111-1691-1 Circuit Breaker allows the user to set the threshold at a level that is suitable for the particular application. It provides quick response to an over-current situation to prevent the system from overloading. In addition, it also provides protection against short-circuits. The adjustable feature also allows the user to tailor the protection level to meet specific requirements.

The APL111-1691-1 Circuit Breaker is a versatile and reliable protection device that is suitable for a wide range of applications, including industrial, commercial and residential applications. It is designed with both high performance and reliable operation in mind. It is also highly cost-effective compared to other similar products on the market. The APL111-1691-1 Circuit Breaker is a reliable and versatile solution for protecting electrical systems from over-current and short-circuit events.
