Circuit breakers are electrical devices designed to protect electrical circuits from potential damage caused by an overload of current. The UPGF6-31868-20 is a type of circuit breaker designed for medium voltage applications. It is a three-phase air-magnetic circuit breaker, which is designed to trip instantly in the event of an overload or short circuit. The UPGF6-31868-20 is suitable for use in various types of installations, including residential buildings, commercial businesses and industrial plants.

The UPGF6-31868-20 is a modular system consisting of the quick break switchgear (also known as the breaker switchgear), the vacuum circuit breaker, the arc chutes, and the auxiliary switchgear. The quick break switchgear is the controlling part of the breaker, in which the contacts are housed in a plastic housing that is sealed and insulated from the environment. The vacuum circuit breaker is the actual switching element of the breaker, which switches on and off depending on the current flow in the circuit. The arc chutes are the protective devices that are placed between the two contacts of the breaker, and they are designed to dissipate the thermal energy created by an arcing fault.

The working principle of the UPGF6-31868-20 is based on the principle of air-magnetic operation. The breaker is designed to trip instantaneously when the current in the circuit exceeds its capacity, and the circuit breaker is designed to provide safety against potential damage and hazards caused by excessive current and heat. The breaker has a built-in device called an arc chute, which is designed to dissipate the thermal energy created by an arcing fault. The built-in device is also designed to create a large spark gap between the contacts of the breaker switchgear, which further helps to reduce the risk of potential damage due to overvoltage.

The UPGF6-31868-20 is suitable for use in a wide variety of applications, including residential buildings, commercial businesses, and industrial plants. It also has the ability to be used in underground and aboveground locations, as well as in outdoor environments. The breaker is designed to provide reliable and continuous performance, and can be used in applications that require a high degree of protection from electrical and mechanical overloads. The breaker is also designed to be easy to install and maintain, and it offers cost-effectiveness compared to other circuit protectors.

In summary, the UPGF6-31868-20 is a type of circuit breaker that is designed to protect electrical circuits from potential damage caused by an overload of current. It works on the principle of air-magnetism, and is suitable for use in various types of applications, including residential buildings, commercial businesses, and industrial plants. The breaker is designed to be easy to install and maintain, and offers cost-effectiveness compared to other circuit protectors.
