Circuit Breakers are often used in the industrial and residential areas where the electricity is subject to fluctuation and interference, as it helps maintain a safe spacing between electric contacts by controlling the flow of power. UPGN666-6792-3 is a special type of Circuit Breaker that provides faithful service by employing special features for higher reliability.

Application Field

The UPGN666-6792-3 Circuit Breaker is mainly used in commercial and industrial applications. It can be used in elevators, automatic teller machines, conveyor belts, air-conditioning systems, and other motorized equipment. It is designed to protect respectively distribution of circuits and motor circuits from overcurrents, short-circuits, and phase unbalance. Additionally it can protect transformer, generators, motors, and other industrial equipment from fire, electrical shock, and other damages caused by sudden power deficiencies.

Working Principle

The UPGN666-6792-3 Circuit Breaker provides reliable protection during overload or short-circuiting currents. This protection is ensured by using thermal or pressure operated devices. Thermally operated devices rely on the principle of “thermal tripping” – changes in temperature due to currents cause a bimetallic strip to bend and upon reaching a certain temperature will trip the circuit breaker. Pressure operated devices use an internal spring and a pressure-sensitive device to trip the breaker if the pressure increases or decreases beyond a certain limit.

UPGN666-6792-3 also has a fail-safe mechanism that will trip the breaker if it detected any fault. If a faulty circuit or equipment is detected, a delayed protective action will be triggered. This gives system operators time to diagnose and repair the fault before the Circuit Breaker is tripped.

The UPGN666-6792-3 Circuit Breaker is also equipped with an alarm function that will sound an audible alert in case of a fault. This alarm helps system operators swiftly respond to the situation.

Conclusion

The UPGN666-6792-3 Circuit Breaker is a powerful and reliable device designed to protect from electrical hazards in commercial and industrial applications. Its special features provide extra protection from sudden power deficiencies, overcurrents, short-circuits, and phase unbalances. In addition to its reliable protection, this Circuit Breaker also features an alarm for early detection of faults and a fail-safe mechanism.
