Item Type: Automatic Transfer Switch_x000D_ Model: LQ3-63 2P_x000D_ Material: PC_x000D_ Rated Voltage: 230V_x000D_ Coil Voltage: 220V_x000D_ Rated Current: 63A_x000D_ Frequency: 50/60Hz_x000D_ Specification: 2P_x000D_ Breaking Capacity: 35KA_x000D_ ATSE: Class CB_x000D_ Rated Current: 63A_x000D_ Size: Approx. 155 x 135 x 114mm / 6.1 x 5.3 x 4.5in_x000D_ Working Principle: _x000D_ The dual power controller and drive mechanism of this series use AC220V power supply, and the power signal depends on the A phase and N line of the input port of the public switch or the standby switch. When the dual power supply is in the automatic state, when the voltage of input phase A and line N of the common switch is normal (AC190-240V), the common switch will be closed preferentially regardless of whether the voltage of public power supply B, C and standby switches A, B, C and N is normal. At the same time, the power indicator and the common closed indicator light are on. When there is no voltage on the incoming line A and N of the common switch, the input of the standby switch A and N is normal. No matter whether the voltage on the normal and standby switches B and C is normal, the dual power supply will be switched to the standby closed. The power indicator and standby closing indicator are on. Manual function, whether the common power supply and standby power supply have voltage or not, can adopt manual operation mode. During manual operation, the manual and automatic buttons shall be placed in the manual operation position. When the handle is rotated clockwise to the terminal, the standby power circuit breaker R is disconnected and the public power circuit breaker N is closed. When the handle is rotated counterclockwise to the terminal, the standby power circuit breaker R is closed and the public power circuit breaker N is disconnected.
