Product Description
I Overview
GCK type low voltage switchgear (hereinafter referred to as the device) is suitable for AC 50Hz, rated working voltage 400V, rated current 4000A and below the low-voltage power grid, for power generation, transmission and distribution system as dynamic lighting, power conversion, Protection and Control and other occasions. All types of devices through pilot projects (TTA) and National Compulsory Certification (CCC), and after a long trial run assessment.
Device complies with GB7251.1-2005 and JB/T9961 standards.
II Environment conditions
- Indoor installation.
- The ambient temperature is not higher than +40 ºC, not less than -5 ºC, and 24h average temperature does not exceed the +35 ºC.
- Air cleaner, the relative humidity at the highest ambient temperature of +40 ºCnot more than 50% in the lower temperature allows a higher humidity, as in +20 ºC, relative humidity of 90%, and allows accidental temperature changes a small amount of condensation produced:
- Altitude does not exceed 2000m.
