A circuit breaker is an electrical device that is designed to prevent circuits from excessive currents, usually resulting from overload, short ciruits, or electrical faults. UPG1-27183-2 is a circuit protector, used widely in various automation systems, providing reliable information and control functions by breaking the load current according to the set parameters in the event of overload, short circuit or other similar situations.

This circuit protector is featured with small size, high capacity and high breaking capability. This will be very useful when high current need to be broken within a limited space.

UPG1-27183-2 is broadly employed in the wide range of applications including power distribution, industrial automation, electronic equipment, lighting control and automation control. Electric fan, air conditioner and heater are the common applications.

The working principle of UPG1-27183-2 is based on the moderate heat generated by the current flow, which will create a hot internal temperature and causes a thermally-sensitive material melt by heating. This will generate contact current loss, then interrupt the circuit and disconnect the power supply. The melting time of the material inside is determined by the design and specific current ratings.

The temperature drop of the thermal material will cause the circuit to become well-connected again and restore the circuit under normal conditions. Accessory indicator and signaling device could be equipped in order to give users visual indication. The temperature could be in a range from -20℃ to 60℃.

The underlying working principle of UPG1-27183-2 is based on the temperature changes. This makes UPG1-27183-2 a suitable and popular circuit protector distinguished from other types of circuit breakers. As well, its applications and benefits makes it widespread in various application fields such as power distribution, industrial automation, electronic equipment, lighting control and automation control.
