Microelectronics technology as the core control technology has been successfully applied in a variety of low-voltage electrical

With the sensor technology, microelectronics technology, low-voltage electrical appliances in the experience from the electronic type electromagnetic development, has begun to enter intelligent. Microelectronic technology as the core control  air circuit breaker  has been successfully applied in a variety of low-voltage electrical , not only improved switching performance, but to some extent also promote the secondary grid  circuit breakers  innovation. voltage air circuit breakers are electrical areas, China is now using ZDS marine DC air circuit breaker protection program has been stuck in a very long time imitation of the former Soviet Union on the product model, application of traditional electromagnetic circuit breaker main problems are: voltage level, current level, breaking capacity is not enough;  power transformers  overcurrent protection current range of motion, lack of precision, reliability is poor; breaker adjustment, repair is not convenient and abroad from the 1990s, the latter began to develop a new generation of AC ACB products are generally achieve high performance, electronic, intelligent, modular, product line, size, variety, wide coverage, able to adapt to low-voltage power distribution, control systems and complete sets of equipment development requirements. developed with electronic overcurrent protection devices or smart breaker breaker breaker breaking capacity increased to improve the overall technical performance has become China's development of marine DC air circuit breakers the inevitable trend.
