Surge protection SZRY1SZRY1 series surge protector for AC 50 or 60HZ, voltage ≤380V the TN-S, TN-C, TN-CS, TT, IT and other power supply system. On the grid due to lightning or surge overvoltage protection. 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 low voltage switch cabinet in effect, used to allocate energy and protect circuits and power supply equipment from overload, under voltage, short circuit, ground fault hazards. Core components of the circuit breaker using computer technology, with many types of intelligent power controller for the user to select low voltage switch cabinet designed for precise selective protection, to avoid unnecessary improve power supply reliability, continuous , while having open communication interfaces and low pressure switch, can achieve the "four remote" low voltage in order to meet the requirements of distribution automation control, the circuit breaker also has isolation. 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." The role of low voltage switch cabinet, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught.
