The SJKW1 series intelligent universal circuit breaker (hereinafter referred to as the circuit breaker) is designed for use in distribution networks with an AC frequency of 50 Hz, a rated voltage up to 660 V (or 690 V), and a rated current ranging from 200 A to 6300 A. It is capable of distributing electrical energy while providing protection against faults such as overload, undervoltage, short circuit, and single-phase grounding. The circuit breaker features intelligent protection functions and precise selective protection capabilities, which enhance the reliability of power supply and prevent unnecessary power outages. Additionally, it is equipped with an open communication interface that supports "four remote" operations, thereby meeting the requirements of control centers and automation systems. The circuit breaker is suitable for installation at altitudes up to 2000 meters, with a pulse withstand voltage of 8000 V (adjusted according to the relevant standards for different altitudes, with the maximum value not exceeding 12000 V). In configurations without an intelligent controller or sensor, the circuit breaker can function as an isolator.
This product complies with international and national standards, including GB14048.2 "Low-voltage Switchgear and Controlgear - Low-Voltage Circuit Breakers" and IEC60947-2 "Low-Voltage Switchgear and Controlgear - Circuit Breakers."
