JCM9LR

JCM9LR series residual current operation circuit breaker, the whole series contains 5 kinds of shell specifications, the current coverage is from 40A-800A, and the products are overloaded and short-circuited. Phase loss, over voltage and under voltage. Residual current, power supply side breaking zero automatic  reclosing, automatic tracking and other protections are integrated, and the breaking capacity reaches 85KA, which ensures the reliable opening of the circuit breaker and minimizes the occurrence of accidents. The intelligent control circuit is composed of a single-chip microprocessor, which automatically displays the  working voltage, current, and real-time residual current value. It can also be equipped with a communication 485 interface, which is convenient for users to operate and control remotely and understand the operating status of the circuit breaker in real time. The integrated residual current operation circuit breaker has the characteristics of small size, convenient installation and use, fixed and adjustable operation value, simple operation, etc. It can be applied to users in various places and various environmental needs, and meets various intelligent requirements of smart grid management, especially It is suitable for comprehensive protection of urban and rural power grids at all levels, and is the first choice for the operation of the national smart grid.
