Na Series Automatic Transfer Switch

Specification of NA Series Automatic Transfer Switch :
1) Rated current of over current release: 40A, 63A, 80A, 100A, 125A
2) Pole number: 2p, 3p, 4p
3) Rated working voltage: AC 400V, 50Hz
4) The total height is only 110mm
5) Good function connection:UTILITY - UTILITY

Features:
1) Provided with such protective functions as checking two sources of voltage at the same time, protection when any one phase or one phase above experiences under- or 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) Four working modes: automatic control, common source (power supply I), standby power supply (power supply II), breaking electricity (re-tripping)
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 supply I automatically throws into supplying electricity; when power supply I has an abnormity, it will automatically transfer to power supply II, when power supply I recovers, it doesn't transfer until power supply II has an abnormity, then it will automatically transfer to power supply.
