SJKW1 series intelligent universal circuit breaker

Scope of application
The SJKW1 series intelligent universal circuit breaker (hereinafter referred to as the circuit breaker) is suitable for distribution networks with AC 50Hz, rated voltage up to 660V (690V) and below, and rated current ranging from 200A to 6300A. It is used to distribute electrical energy and protect lines and power equipment from the hazards of overload, undervoltage, short circuit, single-phase grounding and other faults. Circuit breakers have intelligent protection functions and precise selective protection, This circuit breaker can improve power supply reliability, avoid unnecessary power outages, and has an open communication interface that can perform "four remote" operations to meet the requirements of control centers and automation systems. The circuit breaker has a pulse withstand voltage of 8000V at an altitude of 2000 meters (adjusted according to standards for different altitudes, with a maximum not exceeding 12000V). It does not come with an intelligent controller or sensor and can be used as an isolator. It is marked as a circuit breaker that complies with standards such as GB14048.2 "Low voltage switchgear and control equipment - Low voltage circuit breakers" and IEC60947-2 "Low voltage switchgear and control equipment circuit breakers"
