LZAQ3 series dual power automatic transfer switch

LZAQ3 series dual power automatic transfer switch is suitable for dual power supply system with AC 50Hz, rated working voltage AC 400V and rated working current from 6A to 63A. It has overload and short circuit protection functions. When the power fails, the transfer switch can automatically complete the conversion from the normal power supply to the backup power supply. This series of products is widely used in petroleum, chemical, docks, hospitals, banks, military facilities, high-rise buildings and other places to ensure continuous power supply in the place.
This series of transfer switches has the characteristics of beautiful appearance, smaller size, easy installation and operation. You can choose a transfer switch with an intelligent controller, which can monitor the three-phase voltage of the common power supply, judge the abnormal voltage and issue a transfer command. You can also add a fire linkage function to receive the signal from the fire host and cut off non-priority loads. The transfer switch complies with the GBIT14048.11-2008 standard.
The transfer switch electrical appliance level is CB level.
