Circuit breakers have long been an important element in the electrical infrastructure, providing both safety and control. The UPGF66-31558-25 circuit breaker is one of the most common types of circuit breakers used in applications today.

Application Field

The UPGF66-31558-25 is a thermal-magnetic circuit breaker, and is designed for closed type distribution panels. It is intended for both industrial and residential applications. This circuit breaker is six inches in length, and has an operating voltage range of between 70-120 volts and a breaking capacity of between 3000 and 63000 amps. It is rated for use with up to 2000 amps of current, and can handle up to 25kVA of power.

The UPGF66-31558-25 is widely used in residential and industrial applications, such as residential homes, industrial facilities, motor control centers, and electric utilities. They are also used to control large electric sump pumps, large air conditioners, and industrial heaters, as well as many other applications.

Working Principle

The UPGF66-31558-25 circuit breaker works by using a thermomagnetically operated switch. This switch is connected to the circuit breaker and is triggered when an overload or short circuit occurs in the circuit. When the switch is triggered, the circuit breaker trips, shutting off the flow of current and thus protecting the circuit from further damage.

The thermomagnetic switch is also connected to a thermal element which is sensitive to temperature changes. As the temperature of the circuit rises, the thermal element will detect the increase and trigger the switch. When the switch is triggered, the circuit breaker will immediately trip.

In addition to the thermal element, the UPGF66-31558-25 circuit breaker also has a mechanical device built into the switch to sense and react to sudden increases in current. This device works by using a magnetic field to detect changes in the current and will trip the circuit breaker when the current exceeds a preset safe level.

Finally, the circuit breaker is also capable of detecting ground faults. A ground fault occurs when the current passes through the earth, rather than through an electric device. When this occurs, the circuit breaker will trip and protect the circuit from further damage.

Conclusion

The UPGF66-31558-25 circuit breaker is a popular choice for many industrial and residential applications. It provides reliable protection against overloads, short circuits, and ground faults. This circuit breaker is designed with a thermomagnetic switch, a thermal element, and a mechanical device to ensure proper functioning and protection for a wide range of electrical applications.
