Height above sea level

less than 1000m

This product should not be used under conditions of fire, explosion, earthquake and chemical corrosion environments.

Special service conditions

Each special service condition should be proposed in advance and confirmed by the manufacturer and user.

The dielectric strength of the air will be reduced in when altitude is over 1000m at site.

If the ambient temperature is over the maximum degree, the capacity of the using current must be lower than the designed currents for both main bus-bar and branching bus bar. The installation of area is propitious to reduce heat.
