Characteristic:1) Rated current of over current release: 40A,63A,80A,100A,125A2) Pole number: 2p,3p, 4p3) Rated working voltage: AC 400V, 50HzFeatures:1) Provided with such protective functions as checking two sources of voltage atthe same time, protection when any one phase or one phase above experiences under-or over-voltage, guide phase2) When two sources have abnormal or faulty tripping (overload, short circuit), thecontroller wont send out the order to realize the protective function of reopeningand closing3) Four working modes: automatic control, common source (power supply I), standbypower supply (power supply II), breaking electricity (re-tripping)4) When the working mode is in the automatic control state, it has two self-throwno self-recover, self-throw, and self-recover functions:a) Self-throw non-self recover: when the device enters the working state, power supplyI automatically throws into supplying electricity; when power supply I hasan abnormity, it will automatically transfer to power supply II; when power supplyI recovers, it doesnt transfer until power supply II has an abnormity, thenit will automatically transfer to power supplyb) Self-throw and self-recover: when the device enters the working state, the commonsource throws into supplying electricity; when power supply has an abnormity,it will automatically transfer to standby power supply; when common power supplyrecovers, it will automatically recover common power supply; but when the standbypower supply has an abnormity, the controller will emit an alarm sound
