Circuit Breakers

A circuit breaker is a device used to protect electrical systems from unexpected high electrical current or overloading, which could caused by short circuits. The 219-2-3633-1 circuit breaker (hereinafter referred to as CB) is a heavy-duty circuit breaker with Multi-rates for the protection of overload, short circuit, poles-miss-match, and specific overvoltage functions for various applications in the electricity supply systems. It is designed with a frame structure composed of base, drive, insulation, and handle.

Application Field

CB\'s are widely used in the electricity supply systems, and can be used to protect transformers, motors, high voltage cables, switch and sub-stations. This type of circuit breaker can handle currents of up to three thousand amps and is able to switch between two different poles.

The CB, often used in communication networks such as the broadcast of aerial television and satellite TV media system, capable of switching on and off the medium’s signal, and thus protect the whole network from lightning strikes, electricity surges, and unpredictable power fluctuation. In industrial scenarios, CB is mainly used for electricity-driven machines’ normal start, protection from overload, and power-off.

Working Principle

The working principle of CBs is based on the fact that when an over-current of electricity passes through, accumulation of heat will occur, resulting in the heating up and/or deterioration of the contacts made between the internal device elements. This, in turn, causes an equilibrium of its internal base pressure which is what triggers the instantaneous breaking of the current path, thus protecting the line.

CBs are broadly classified into two categories: one with an “on-off” switch and a make contact with and the other with an “on-off”, a make contact and a break contact.

When the reaches the operating temperature, the CB will operate of its own accord and turn off the current in the circuit. If the current has to be switched on again, it must be manually reset.

The CB is also equipped with special fault protection expertise to avoid the spread of current in the event of a fault. This makes it an important safety Device when handling electricity in industrial and residential buildings.

Conclusion

The 219-2-3633-1 circuit breaker is ideal for electric power supply systems and communication networks. It is designed to offer overload, short circuit, poles-miss-match, and specific overvoltage protection functions while offering a heavy-duty frame structure composed of a base, drive, insulation, and handle. It swiches on and off the medium’s signal, and has a make contact and a break contact which is triggered at a certain point when the CB operates at a certain temperature. The CB works well in industrial and residential buildings and is a crucial safety Device.
