225A 630A 4P Automatic Power Distribution Switchgear Generator Auto Changeover Switch
GTQ2Z series automatic transfer switch (ATS) is suitable for the transfer between two power sources, common source (power supply ) and standby power supply (power supply ),whose rated voltage is below 50Hz,400V (AC) when one power supply malfunctions to assure the safe. and stable power supply. The setting mainly used for hospital, shopping center, bank, and chemical industry, metallurgy, high building, military facilities etc. important situation where power breaking can't be allowed.

1. Provided with such protective functions as checking two sources of voltage at the same time,pr-otection when any one phase or one phase above experiences under over-voltage, guide phase.
2. When two sources have abnormal or faulty tripping (overload, short circuit), the controller won't send out the order to realize the protective function of reopening and closing.
3. Six working modes: manual control, self-throw self-recover, common source (power supply I), standby power supply (power supply ), breaking electricity and re-tripping,self-throw no self-recover.
4. When the working mode is in the automatic control state, it has two self-throw no self-recover, self-throw, and self-recover functions:
a) Self-throw non-self recover: when the device enters the working state, power supplyautomati-cally throws into supplying electricity; when power supply has an abnormity, it will automatically transfer to power supply ; when power supplyrecovers,it doesn't transfer until power supply has an abnormity, then it will automatically transfer to power supply.
b) Self-throw and self-recover: when the device enters the working state, the common source throws into supplying electricity; when power supply has an abnormity, it will automatically transfer to standby powersupply; when common power supply recovers,it will automatically recover common power supply;but when the standby power supply has an abnormity, the controller will emit an alarm soured.
