Front Connect Dual Power Automatic Transfer Switch (Q8-63IIA/3P)

Product Description

1.Application
Q8 Series as main and standby dual power automatic switch adopts electromagnetic drive, electrical and mechanical inter-locking mechanism. The main circuit contacts are static and dynamic. The movable contacts are V-shaped. In order to avoid long-term electrification of electromagnetic coils, electric closing and mechanical maintenance are adopted. Therefore under steady-state working conditions the operating mechanism doesn't need to provide working current and energe saving is remarkable. The control power are from the main power supply of AC 220V (without additional control current).  Because of its superior structure, the main and standby power supply will not be connected at the same time to ensure  the main and standby power works reliably and does not interfere with each other. The switch has electrical or mechanical closing  instructions, at the same time it can provide customers with nomal opened and normal closed passive contacts for other purposes.
