991201 Circuit Protection

Circuit Breakers

Circuit Breakers have enabled us to make significant advances in the industrial, commercial, and residential sectors. As the name implies, a circuit breaker is an electrical device that can open and close the main switch in an electrical circuit. Today, circuit breakers are used in applications ranging from power distribution systems to appliance and lighting controls.

991201 Application Field and Working Principle

The 991201 circuit breaker is primarily used to control and protect electrical circuits in residential and industrial environments. The device is composed of a plastic enclosure containing a specially designed electrical element, such as a relay, and a number of contactors. These contactors are connected to the main switch of the circuit and to the primary fuse panels of the power distribution system.

The relay of the 991201 circuit breaker can be programmed to open the main switch in the event of an overload or short circuit. The device is designed to automatically reset itself after the fault is cleared. The relay can also detect the opening and closing of doors, windows, or other similar objects. In addition, the device can be used to control lighting systems and appliance circuits.

The 991201 circuit breaker is designed to perform various protective functions. Its main purpose is to prevent current overloads by automatically opening the main switch when the current load increases to an unsafe level. This helps to reduce the possibility of electrical fires. Additionally, the device has the ability to detect short circuits and open the main circuit as soon as the fault is detected. This helps to protect the wires and other components from further damage caused by the short circuit.

The 991201 circuit breaker also enables the user to manually reset the device. This can be done by pushing the red reset button. This resetting action can be initiated each time the device trips due to an overload or short circuit. Additionally, the 991201 circuit breaker can be programmed to perform some additional protective functions. These include providing protection against phase reversal, under-voltage, and over voltage.

In conclusion, the 991201 circuit breaker is an essential device for controlling and protecting electrical circuits in residential and industrial environments. The device helps to protect against electrical fires, short circuits, and phase reversal. In addition, the device can be programmed to perform additional protective functions. The device is designed to automatically reset itself after a fault is cleared and can be manually reset when necessary.
