Circuit Breakers

The UPG30-1REC5-27511-1 is a miniature circuit breaker used in electrical systems to provide vital short-circuit and overload protection. It is able to sense an electrical current that is deemed unsafe and “trip” when a fault is detected. This action helps to protect the wiring system in the event of a short circuit or an overload, preventing serious damage or risk to people and property.

Application Field

The UPG30-1REC5-27511-1 miniature circuit breaker is mainly used in residential and commercial settings. It can be used in single-family homes to protect the main breaker panel. In commercial settings, it is used in small and medium-sized businesses, and can be used in different panel boards that receive power from the main circuit breaker. Apart from this, it can also be used in small appliances such as refrigerators, air conditioners, and washing machines.

Working Principle

The UPG30-1REC5-27511-1 miniature circuit breaker has a metal element called a bimetal strip, which is connected to the live side of the circuit. The bimetal strip heats up when a safe current limit is reached and deflects, causing the circuit breaker to trip. Initially, the connection point between the circuit and the bimetal strip is covered by an insulating material, separating live and neutral wires. When the circuit senses a current in excess of its rated limit, the insulating material melts and the connection is made, and the current runs through the bimetal strip. As the current increases, so does the temperature of the bimetal strip, and when the preset maximum temperature has been reached, the strip will deflect, interrupting the circuit and tripping the breaker.

The UPG30-1REC5-27511-1 miniature circuit breaker is a reliable device designed to protect wiring systems from dangerous electrical overloads. It is suitable for any residential or commercial application where a small circuit breaker is needed. Its operation is based on a simple but effective bimetal trip principle, making it a dependable and economical choice for system protection.
