Automatic Transfer Switch
Automatic Transfer Switch: ZSEE KE series is suitable for AC 50Hz, with a rated current of 16~630A and a rated operating voltage of AC400V in power distribution systems. It can handle the transfer between the main power supply and backup power, making it suitable for important power systems where power outages are not permitted.
This series of switches features an integrated three-position design, classified as a CB-grade device. The motor-driven system allows for both manual and automatic power switching and supports functions such as loss of voltage, over/under voltage, and phase failure detection.
The switch is compact, easy to install, and widely used in industries like industrial, construction, petroleum, and chemical sectors.

ZSEEKE Terminal and Wiring Instructions
Note:
-
Terminals 101~103 and 201~203 are active output contacts (AC230V/0.5A, no external power required);
-
For three-pole switches, terminals 101 and 102 are neutral line terminals, and the local neutral line bus must be connected to enable the automatic transfer function.
Note:
-
Terminals 101~104 and 201~204 are active output contacts (AC230V/0.5A, no external power required);
-
In the mains-generator mode, terminals 301~302 input DC power (DC24V), and the startup delay function (adjustable from 0 to 180s) is initiated; if no power input, the delay is set to 0s;
-
Terminals 501~503 are the generator startup control signal outputs;
-
For three-pole switches, terminals 1N and 2N must be connected to the local neutral line bus to enable the automatic transfer function.
