Intelligent Universal Breaker SZRW8SZRW8 series intelligent universal circuit breakers for AC 50Hz, rated current 400A ~ 6300A, rated insulation voltage 1000V, rated working voltage distribution network 400V, 690V is used to distribute energy and protect circuits and power equipment from overload, under - voltage, short circuit, grounding faults. Core components of the circuit breaker using computer technology, with many types of intelligent controllers for users to choose, Kaifeng low voltage switch, enabling precise selective protection, to avoid unnecessary power outages, low voltage, improve power supply reliability, continuity, Qingfeng low voltage, while having open communication interface, can achieve the "four remote", Gongyi City, low voltage, power distribution automation and control to meet the requirements of the circuit breaker also has isolation function . Standard: GB14048.2-2008 "low-voltage switchgear and control equipment, low-voltage circuit breakers", identical with IEC60947-2 "low-voltage switchgear and control equipment Part 2 breaker." Standard low voltage electrical products and low voltage electrical standard content typically includes the use of products, the scope of environmental conditions, technical performance requirements, test items and methods, packaging, transportation requirements, and it is the manufacturer and user acceptance basis. Standard nature of the content can be divided into basic standards, professional standards and product standards three categories. According to the approved standard content level properties can be divided into: National Standard (GB), the Department of Standards (JB) and the Bureau approved corporate standards (JB / DQ) three low voltage switch procurement, learning Connaught Electrical and Mechanical (online consultation), low voltage By Henan Xi Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
