UPL115-1RE-6129-1 Circuit Protection

Circuit breakers are essential components for electrical panel installations, providing protection against power faults and circuit overloads. UPL115-1RE-6129-1 is a single-pole thermal-magnetic circuit breaker with an adjustable trip current up to 125 Amperes (A) and rated voltage of 230/400VAC. This breaker is designed for polespecific installation, meaning it should only be installed into one pole. It can also be used in a variety of industries, including commercial, institutional, and industrial. In this article, we will discuss the application field and working principle of UPL115-1RE-6129-1.

The UPL115-1RE-6129-1 circuit breaker is designed to be used for a variety of applications, including industrial motor control, lighting control, HVAC systems, and other electrical devices. Its thermal-magnetic trip current feature allows it to be used for detecting short-circuits and overcurrents. The adjustable trip current can be set to suit specific continuous and short-circuit loads, providing enhanced protection against overcurrents and short circuits. This breaker also has a wide voltage tolerance, allowing it to be used with AC and DC circuits.

The working principle of UPL115-1RE-6129-1 circuit breakers is based on thermal-magnetic operation. When an overcurrent situation occurs, the heat generated by the current flow causes the bi-metallic strip of the circuit breaker to expand. This expansion causes the contact-tip of the breaker to move, opening the circuit and stopping the flow of current. The magnetic element of the circuit breaker uses a trip-coil, which is magnetized when the current flow exceeds a certain threshold. This trip-coil causes the contact-tip of the breaker to open, interrupting the flow of current. The adjustable trip current setting allows the user to set the current threshold for trip operation.

In addition to the thermal-magnetic operation, UPL115-1RE-6129-1 circuit breakers also feature overload and short-circuit protection. The overload protection feature monitors the flow of current and trips the breaker if the current exceeds the pre-set threshold. The short-circuit protection feature detects any sudden current surge and trips the breaker to interrupt the flow of current. When this breaker trips, it will remain open until manually reset.

UPL115-1RE-6129-1 circuit breakers are a reliable and cost-effective solution for a variety of electrical applications. With its adjustable trip current setting, overload protection, and short-circuit protection, it provides enhanced protection against power faults and circuit overloads. It is suitable for both industrial and commercial use, making it a versatile and dependable option for any electrical installation.
