UPL11-2240-2

Circuit breakers are an important part of electrical safety. They act much like fuses, tripping when an excessive current flows through them, thus protecting circuits from short-circuits, overloads, and other hazards. A UPL11-2240-2 is a type of circuit breaker designed for low- and medium-voltage applications. These breakers can be used to protect residential, commercial, and industrial machinery, as well as power distribution systems. They are a reliable choice for a wide variety of applications.

The UPL11-2240-2 circuit breaker is an insulated-case, 2-pole breaker. It is rated for 240V AC voltage and 10A current, making it suitable for both low- and medium-voltage applications. It is design certified according to UL 489 requirements, meaning it has met the safety requirements of the Underwriter\'s Laboratories. In addition, the UPL11-2240-2 has Type 2 coordination, meaning that it is designed to protect itself and downstream equipment from overcurrents.

The working principle of the UPL11-2240-2 circuit breaker is simple. The breaker monitors the current flow in a circuit, tripping to open contact points if an overcurrent is detected. When the circuit breaker trips, the excess current stops flowing, thus protecting the circuit and its components from being damaged by high voltages. The breaker operates using a bimetallic strip, which warps when an overcurrent is detected, or when the temperature of the circuit exceeds a certain limit. This warping of the strip causes a interruption of the connection, which results in a tripping of the breaker.

The UPL11-2240-2 circuit breaker is designed for a variety of residential, commercial, and industrial applications. It is commonly used in panelboards, switchboards, motor control systems, and other equipment to protect against overloads or short circuits. It is also used to protect machinery and other equipment from voltage spikes or surges, such as those caused by lightning strikes or high peak demands. In addition, the breaker is capable of monitoring and tripping in the event of a ground fault, providing an additional layer of safety.

The UPL11-2240-2 is a reliable choice for a wide range of low- and medium-voltage applications. Its versatility and safety features make it an ideal choice for a variety of applications, from residential power systems to industrial machines. By providing protection against overloads, short circuits, and other electrical hazards, the breaker can help ensure the safe operation of equipment and prevent costly electrical damage. With its compact design, the UPL11-2240-2 is well suited for both new construction and retrofitting existing systems.
