Circuit breakers are essential pieces of equipment when it comes to electrical safety. They protect circuits from damage due to short circuits and other electrical hazards, ensuring reliable operation of devices and equipment. The APGN666-9094-4 is a circuit breaker manufactured by Prespa Electric Company. It is an air-break circuit breaker designed for use in secondary distribution systems.

The maintenance-free operation of the APGN666-9094-4 is what sets it apart from other circuit breakers of the same type. Its high-speed circuit-breaking capacity is obtained using a three-component system consisting of a Auxiliary Contact, a DC-contact system, and a surge arrester. The Auxiliary Contact is a complex contact system that acts in a manner that is similar to a micro-switch. The DC-contact system is designed to detect the current of the primary circuit in order to avoid damage to the contacts of the breaker during operation. The surge arrester is responsible for protecting the circuit breaker from high-voltage surges.

The APGN666-9094-4 is designed for use in secondary distribution systems such as residential households, commercial establishments, and industrial settings. Its advanced features include: an automatic over-voltage protection system, an auto trip interruption system, and an auto-reset protection system. These features ensure maximum safety and reliability in the event of an electrical fault. The auxiliary contact can also be used to perform a short-circuit protection by shutting off the power automatically when the currents in the protective circuit exceed the limits. This feature is especially useful in settings that experience frequent electrical faults.

The APGN666-9094-4 circuit breaker is designed for use in a wide range of applications. It is suitable for use in residential households, commercial establishments, and industrial settings. It is also suitable for use in applications that require the monitoring and control of electrical circuits including those related to power generation, building automation, fire alarms, lighting systems, and security systems. It is also suitable for use as an emergency power generator in an off-grid setting, where the engine-driven generators are used as a backup power source.

The APGN666-9094-4 is also suitable for use in hazardous locations, such as those involving volatile or flammable substances. Its high-speed operation and automatic over-voltage protection system ensures that the circuit breaker can provide reliable protection in such environments. Due to its superior performance, the APGN666-9094-4 is a trusted choice for many industrial, commercial, and residential applications worldwide.
