All Types Geya Air Circuit Breaker (ACB)

GYDW1 series intelligent circuit breakers(hereinafter referred to as circuit breakers), are suitable for distribution networks of AC 50HZ, rated voltage up to 660V(690V)and rated current of 630A-6300A, and are used to distribute electric energy and protect the circuit and power supply equipment from overload, under-voltage, short circuit, 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 the unnecessary power failure. Meanwhile, it is equipped with open communication interfaces, which enable the”four remote “functions, meeting the requirements of the control center and automation system. The impulse withstand voltage of the circuit breaker at an altitude of 2, 000 meters is 8, 000V(the voltage varies with different altitudes according to relevant standards, and the maximum value is 12, 000V). When it is not equipped with any intelligent controller and sensor. the circuit breaker can be used as an isolator with the mark. The circuit breaker complies with the requirements of the standards GB140482″Low voltage switchgear and controlgear- Part 2: Low voltage circuit-breakers and EC60947-2 Low-voltage switchgear and controlgear-part 2:Circuit-breakers”etc

Why Geya Air Circuit Breaker (ACB)

  • Intelligent control function: under-voltage 0 time (timed delay) release, shunt release.
  • Multiple protection: overload (with alarm), under voltage, short circuit, single phase grounding.
  • Display function: display of setting current and voltage in each phase.
  • Self-inspection function: over-heat self-inspection and microcomputer self diagnosis.

  • Ambient air temperature
    The ambient working temperatures shall not be higher than + 40 c or lower than -5 c and the average value of 24h
    shall not be higher than 35℃
    Note: If user’s ambient working temperature exceed required values , they should discuss it with our company.
  • Atmospheric conditions
    The atmospheric relative humidity should not be higher than 50 when the ambient working temperature is 40 ,and should be
    comparatively higher in case of low working temperature , the maximum average relative humidity in the wettest month is 90%
    , and meanwhile the minimum average temperature of this month is+25 ,considering the condensation on product surface
    due do to temperature changes . If user’s working conditions cannot meet the above-mentioned requirements, please discuss
    with our company.
