CW1 series intelligent universal circuit breaker (hereinafter referred to as circuit breaker), Apply to 50Hz AC, Rated voltage to 660V (690V) and below, in the distribution network with rated current of 200A ~6300A, circuit break used to distribute electric energy and protect circuit and power equipment from overload, undervoltage, shortcircuit, single-phase grounding and other faults has intelligent protection function. Selective protection is accurate, it can improve the reliability of power supply, avoid unnecessary power failure, and has an open communication interface. It can carryout "four remote" to meet the requirements of the control center and the automation system. The circuit breaker has a pulse withstand voltage of 8000V at an altitude of 2000 meters (the maximum withstand voltage is not more than 12000V according to the standard for different altitudes).
The circuit breaker can be used as an isolator without intelligent controller and sensor, and is marked as -*The circuit breaker conforms to GB14048.2 "Low Voltage Switchgear and Control Equipment Low Voltage Circuit Breaker" and EC60947-2 "Low Voltage Switchgear and Control Equipment Circuit Breaker" and other standards.
