Traditional circuit breakers only have the function of protection, while traditional contactors only have the function of line conversion.
Is there a device that can achieve both automatic protection and remote control of circuit state transition? The answer is yes, the traditional aviation power distribution industry has developed RCCB (Remote Control Circuit Breaker) to address the drawbacks of thick and heavy wires in the high-power transmission circuit of large passenger aircraft.
For example, circuit breaker manufacturers such as Eaton's SM600 and SM601 series from the United States and E-T-A's 4930 series from Germany are both based on thermal circuit breakers and linear motors for remote control. Their product protection features comply with MIL-PRF-83383 standards
And for example, the CC04 series products produced by Leach, a subsidiary of Esterline in France, are equipped with sensors and control circuits to achieve overcurrent protection on the basis of Bus bar contactors. Zodiac in France has also produced similar products, which have a higher overcurrent capacity and slightly heavier weight than RCCB based on circuit breakers.
As shown in the following figure:
A is a distribution system that does not use RCCB
B is a distribution system using RCCB
From the above figure, it can be seen that the use of RCCB distribution lines has played an irreplaceable role in reducing device costs, simplifying wiring, and reducing overall weight. The cost-effectiveness of the entire machine has also been greatly improved.
