GSA1 Series Automatic Transfer Switching Equipment
—* APPLICATION
^ Sfix ftlv /S^W©JlMm^fiSa5ffl^gmo
GSA1 series automatic transfer switching equipment is used to shift
from the abnormal power supply to in case of one line of abnormal power
supply ( normal power supply and standby power supply or normal power
supply and the generating power supply), both of which have the rated
operational voltage of AC400V, 50Hz,rated current of 1 OA to 800A , So that
reliablity and continuous are ensured . this switch with undervoltage ,
overvoltage phaes missing,overload and short circuit protection . this
swith often used in hospitalsx shopping mallsx banksx chemica
ndustryx metallurgy .building other importanr sites electricity.
