Service Conditions
The fol lowing parameters define the u sual service conditions
under which the ci rcuit breakers shall be considered su itable
for operating at their standard ratings. Conditions of use be
yond these l i mits m u st be g iven special consideration, con
sultation with the factory or reference to the IEEE Application
Guide, ANSI C37 010

Altitude
Unusual service conditions which expose the equipment to
d ust, steam, salt s pray, corrosive gases, d ripping water, vibra
tion, shocks , high and low temperatu res, high altitudes and the
like may req u i re special construction. Refer concerns to the
factory.
The values of insulation level compiled above are referred to
sea level in accordance with ANSI C37. 04-1979 consolidated
standards . The higher the site altitude, the lower the insu lating
capacity of the air. The decrease i n insulating capacity is ne
g lected by standards for altitudes of up to 3 ,300 ft. ( 1 000m)
above sea level. For hig her altitudes, the values of low-fre
quency withstand voltage, impulse withstand voltage and rated
continuous cu rrent must be corrected in accordance with ta
ble 2 .
