Circuit breakers are vital components in electronic systems, providing the ability to prevent overloads and provide isolation of system components from potentially damaging currents.

UPG1-25758-3 application field and working principle is an example of a circuit breaker technology. It is designed for use in high-voltage applications, such as industrial power systems, and acts as a switch to isolate or restore main circuit power. The circuit breaker is equipped with an arc-detection system that detects arcing within the breaker circuits, and trips the breaker when an excessive current is detected, preventing further damage.

The UPG1-25758-3 utilizes a three-stage design, combining a power diode, a current controlled switch and an arc detection circuit. When the breaker is in the closed position, two power diodes Is and Im are connected in series so that the current flows through the diodes and into the control switch. If an arc is detected on the switch, a voltage will be read across the two diodes and this will be sent back to an integrated circuit. The circuit will track the arc current and when an excessive amount is detected, it will activate the control switch to trip the circuit breaker and thus preventing any further damage.

The UPG1-25758-3 is also designed to detect and respond to any other source of overcurrent. It features a fault detection circuit that monitors the current and voltage of the line. If the current or voltage exceeds the set limit, the device will react accordingly and trip the circuit breaker.

The UPG1-25758-3 is an innovative and cost-effective solution for applications that require reliable overcurrent protection. It is suitable for use in typical motor control circuits, power distribution systems, and other industrial applications. The device is designed to offer reliable trip time and high contact capacity, as well as providing comprehensive protection from overcurrents, including short circuits and arc faults.

The UPG1-25758-3 provides a useful addition to the range of circuit breaker technologies available on the market, offering cost-effective and reliable protection for electronic systems. It is designed to provide a safe and cost-effective solution for preventing potentially hazardous overloads.
