Introduction

Circuit breakers are electrical devices used to protect against electrical over currents, under currents, and short circuits. They are designed to quickly shut off the flow of electricity in either an electrical system or individual circuits in order to reduce the chance of damaging the system or equipment due to a power surge. The 991260 application field and working principle is one type of circuit breaker. This article will discuss the 991260 application field and its working principle.

The 991260 Application Field and Working Principle

The 991260 application field is motor control circuits, distribution lines, and motor starting and protection. It is frequently used in the industrial and commercial markets. This type of circuit breaker is designed to protect against short circuits, line faults, and over loading. The 991260 application field is also used in power distribution circuits, industrial control panels, and O/V (overvoltage) protection.

The 991260 circuit breaker has a two-phase working principle. The first phase is the protection phase. When an over current or short circuit occurs the circuit breaker trips and the contacts open, disconnecting the circuit. In this phase, the magnetic forces generated by the current will act on the moving trip levers and open the contacts of the circuit breaker, and, in turn, disconnect the circuit.

The second phase is the reset phase. Once the 991260 circuit breaker has opened, it must be reset before it can be used again. This is done by manually turning on the reset switch. Once the reset is complete, the circuit breaker is then free to be used again.

The 991260 has two features that makes it unique. One, it has a short-circuit current protection feature and two, it has a high efficiency undervoltage protection feature. The short-circuit current protection feature safeguards the circuit breaker from excessive short-circuit currents. The undervoltage protection feature prevents the circuit breaker from closing while the voltage drops below a predetermined level.

Conclusion

The 991260 application field and working principles are unique and beneficial. They are frequent used in the industrial and commercial markets. They are designed to protect against short circuits, line faults, and overloading. They have a two-phase working principle which include protection and reset. Protection is done by disconnecting the circuit when an over current or short circuit occurs and reset is done by manually turning on the reset switch. They have a short-circuit current protection and high efficiency undervoltage protection feature.
