HKKM1E electronic moulded case circuit breaker series
General:
It has functions of overload long delay inverse time lag, short-circuit short delay inverse time lag, short-circuit short delay definite time lag, short-circuit instantaneous and under-voltage protections . It protects the circuitries and power equipment from being damage, enjoys complete and accurate protection functions that improve reliability of power supply, preventing from unexpected power failure. The controller with communication interface also can realize 'four-remote operation' that meets the requirements of the control center and automation system.
