AM1E series intelligent moulded case circuit breaker is developed and manufactured by adopt-ing international advanced technology.It is supplied with rated insulating voltage 800v and usedfor circuit of AC 50/60Hz, rated operating voltage 40oV, rated operating current up to 80O0A of thecircuit breaker infrequent changing over and starting of the motors.The circuit beaker has protec-tion function of overload long delay inverse time, short circuit short delay time limit, short circuit in-stantaneous and under voltage,which can protect the line and power supply equipment from dam-age. The circuit breaker can be mounted vertically(i.e. vertical) or horizontally. The Circuit breaker cannot be poured into the line, that is, only 1,3,5 connect power cord;2,4,6 connect load line,
