Circuit breakers are one of the most important parts of the power distribution system. The UPGHF66-30424-38 is one of the types of circuit breakers available in the market. It is designed for residential and commercial applications and provides reliable performance to protect and manage the electrical circuits. This article provides an overview of UPGHF66-30424-38 application field and its working principle.

Application Field

The UPGHF66-30424-38 circuit breaker is suitable for application in: Industrial, commercial and residential buildings. This breaker is designed for the 250VAC AC circuit up to 24A. The device is equipped with a thermal trip unit, which provides overcurrent protection. The UPGHF66-30424-38 is available in 1P, 2P and 4P configurations. The breaker can be used as a self-powered device or to be connected to an external power circuit.

The UPGHF66-30424-38 has a wide range of cutting power which includes AC, DC, non-linear load, as well as pulsed circuit and wide frequency range. It is also suitable for controlling unbalanced load even with high harmonic distortion. The UPGHF66-30424-38 offers a high level of safety and reliability thanks to the advanced internal protection provided by the thermal trip element.

Working Principle

The UPGHF66-30424-38 circuit breaker has a magnetic field that is responsible for the circuit protection. The magnetic field helps to detect and break off the current flow through the circuit. The UPGHF66-30424-38 also uses a thermal trip unit, which monitors the current flowing through the circuit breaker, and opens the circuit when the current is too high. This helps to prevent any electrical fire or other incidents due to an overload of the circuit breaker.

The UPGHF66-30424-38 has a bi-metallic thermal trip element, which is responsible for sensing the current flow through the breaker. The bi-metallic element is made up of two dissimilar metal plates that will expand due to an increase in temperature. The increased expansion will cause the circuit breaker to trip and open the circuit, disconnecting the power supply. The bi-metallic element is calibrated at the factory for a specific temperature and current range.

The UPGHF66-30424-38 also has an auxiliary switch, which is used to control its operation. The switch is designed to detect a fault in the circuit and close the circuit, allowing the breaker to trip. This helps to isolate a faulted circuit and prevent any dangerous incidents.

The UPGHF66-30424-38 circuit breaker is designed to provide reliable protection for the electrical circuits in residential and commercial buildings. It is designed to detect and break off current through the circuit, and uses a bi-metallic element to trip the circuit breaker in case of an overload. The breaker also has an auxiliary switch that helps to detect and isolation faults. The breaker is available in 1P, 2P and 4P configurations, which makes it suitable for a variety of applications.
