Circuit breakers are essential components of electrical systems, designed to protect electrical equipment from becoming overloaded. UPGH111-1REC2-2919-17 is one of the most popular circuit breakers in the market. It is a three-pole breaker with a voltage rating of 120/240V and a 3mA trip rating. In this article, we will discuss the application field and working principle of UPGH111-1REC2-2919-17.

UPGH111-1REC2-2919-17 is typically used in residential, commercial, and industrial applications. This type of circuit breaker is suitable for single-phase power distribution, low voltage, and current protection. In residential applications, it is used to connect and disconnect homes from the electrical service, as well as to control appliances such as air conditioners, stoves, and refrigerators. In commercial and industrial environments, it is used to protect motors, lighting circuits, and other devices from power surges while also providing overload protection.

The working principle of UPGH111-1REC2-2919-17 is quite simple. It consists of a contact-bearing assembly, a trip mechanism, and a mounting bracket. The contact-bearing assembly is composed of two insulated metal contact bars, which make contact with each other when the breaker is closed. When the current passing through the breaker exceeds the rating of the breaker, the trip mechanism is activated and the bars are forced apart, thus breaking the circuit. The mounting bracket is the mechanism that holds the breaker in place.

In addition to its primary function of protecting electrical equipment from overloads, UPGH111-1REC2-2919-17 also protects against short circuits and ground fault currents. A short circuit occurs when an indefinite amount of current flows through the circuit, causing the circuit breaker to open. A ground fault occurs when an excessive amount of current flows through the ground wire, causing the breaker to open.

To sum up, UPGH111-1REC2-2919-17 is a highly reliable and cost-effective circuit breaker. Its use in residential, commercial, and industrial applications ensures that electrical equipment is protected from potential danger of overloads, short circuits, and ground faults. Furthermore, understanding its working principle helps users to troubleshoot and diagnose issues with the circuit breaker.
