Introduction
Circuit breakers are a key part of the infrastructure of any power system, and are used to protect the system from overload or other faults in the system. The UPGH12-8535-2 is a UL 1077 and UL 1083 rated circuit breaker that offers protection from overvoltages and other hazardous conditions. This paper will discuss the application field and working principle of the UPGH12-8535-2 circuit breaker.

Application Field
The UPGH12-8535-2 is designed for use in traffic signals, lighting systems, fire alarm systems, elevators, machinery, and other applications where overvoltages can occur. This breaker has a continuous current rating of 12.5A and a maximum voltage rating of 600VAC in two-pole applications. The breaker is available in both single pole and double pole configurations, and is suitable for use in a number of different locations where overvoltage protection is required.

Working Principle
The UPGH12-8535-2 circuit breaker is designed to provide overvoltage and other hazardous condition protection in the event of a fault or overload in the system. When an overvoltage condition is detected, the breaker trips, disconnecting the power supply to the protected circuit. This prevents further damage to the system by avoiding a surge or overcurrent on the circuit. The breaker also features an adjustable trip threshold, which allows the user to customize the protection level for a given application.

Testing and Listings
The UPGH12-8535-2 is UL 1077 listed, meaning that it has been tested according to stringent criteria and has passed all the required safety tests. It is also UL 1083 listed, meaning that it meets the requirements for installation and use in traffic control systems. Furthermore, the breaker has been tested and approved by the National Fire Protection Association.

Advantages
The UPGH12-8535-2 circuit breaker offers several advantages over traditional overvoltage protection devices. It is designed to provide reliable protection against overvoltage and other hazardous conditions in applications where failures could result in costly damage or downtime. The breaker is also UL 1077 and UL 1083 listed, which provides peace of mind and assurance that the device will function as expected in normal operating conditions. Additionally, the adjustable trip threshold allows the user to customize the protection level for a given application. Finally, the breaker is approved by the National Fire Protection Association, demonstrating its reliability in critical fire safety applications.

Conclusion
The UPGH12-8535-2 circuit breaker is designed for use in applications where overvoltages can occur, such as traffic signals, lighting systems, fire alarm systems, elevators, and machinery. The breaker features an adjustable trip threshold which allows the user to customize the protection level, and is UL 1077 and UL 1083 listed as well as being approved by the National Fire Protection Association. With its reliable protection, versatility, and ease of use, the UPGH12-8535-2 circuit breaker is an ideal choice for any application requiring overvoltage protection.
