Q3W Type AC Automatic Change over Switch 1A~63A  Application

Q3W-63 series automatic transfer switch is designed and developed by our company according to universal

customers’ requirements.This switch uses DZ47 miniature circuit breaker (improved type)as the actuating element

is equipped with the new type control mechanism. With the smallest volume among the similar products it also has

the functions like the fire control and power generation, and it is specially used in the important power supply locations

where the power failure is not allowed.

Q3W-63 series automatic transfer switch is mainly made up of power transfer actuating breaker

(including normal power actuating breaker QN and reserve power actuating breaker QR, one for each)

automatic controller, electric operating mechanism and so on. Wherein, the circuit breaker QN and QR retains

the original over-current protection and short-circuit protection.

Q3W Type AC Automatic Change over Switch 1A~63A  Specification

Q3W-63 series automatic transfer switch can adopt the manual operation mode when the manual operation is used

the manual/auto button is set in the “manual” position when the handle is rotated clockwise to the terminal

thus, the reserve power actuating breaker QR is switched off, and the normal power actuating breaker QN is switched on.

On the contrary when the handle is rotated CCW to the terminal, the reserve power actuating breaker QR is switched on

and the normal power actuating breaker QN is switched off. The panel power indicating lamp (yellow) indicates

the working voltage of automatic controller, if this lamp is not brightened, this means the working power of automatic 

controller has the failure, and the switch should not be operated. After it is recovered, the manual/auto button should

be set to the automatic position if the normal power is in the normal state, the normal power actuating breaker QN will

be in the ON state, thus, the panel N power indicating lamp (green) is brightened; if the normal power is abnormal

the normal power actuating breaker QN will be in the OFF state and reserve power actuating breaker QR will be in the ON

state, thus, the panel R power indicating lamp (green) is brightened.
