Product Description:

PAC series intelligent universal circuit breaker (hereinafter referred to as circuit breaker) is applicable to the power distribution network with AC 50Hz, rated voltage up to 660V (690V) and below, and rated current 630A~3200A. It is used to distribute power and protect the line and power equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. Circuit breaker has intelligent protection function, selective protection is accurate. It can improve the reliability of power supply and avoid unnecessary power outage. At the same time with open communication interface. The circuit breaker can be "four remote" to meet the requirements of the control center and automation system pulse voltage 8000V at the altitude of 2000 meters (different altitudes according to the standard correction, the maximum is not more than 12000V). The circuit breaker without intelligent controller and sensor can be used as an isolator.

The circuit breaker complies with the GB/T14048.2 standard.
