Air Circuit Breaker (ACB) Manufacturer

GYW1 series intelligent circuit breakers (or referred to as circuit breakers) are suitable for distribution networks of AC 50HZ, rated voltage up to 660V (690V) and rated current 630A-6300A. They are used to distribute electric energy and protect the circuit and power supply equipment from overload, under-voltage, short circuits, single-phase grounding and other failures. The circuit breaker has the intelligent protection function, of which the selective protection is accurate, enhancing the power supply reliability and avoiding unnecessary power failure. Meanwhile, it has open communication interfaces, which enable the” four remote “functions, meeting the requirements of the control centre and automation system. The impulse withstands voltage of the circuit breaker at an altitude of 2000 meters is 8,000V (the voltage varies with different altitudes according to relevant standards, and the maximum value is 12 000V). We can apply the circuit breaker as an isolator with the mark in the absence of the intelligent controller and sensor. The circuit breaker complies with the requirements of the standards GB140482″Low voltage switchgear and control gear- Part 2: Low voltage circuit-breakers and EC60947-2 Low-voltage switchgear and control gear-part 2:Circuit-breakers” etc.
