3 Phase Automatic Transfer Switch 400A

Product Introduction
SQ5 series Automatic transfer switch mainly used for distribution or electromotor network, which under voltage 380V, rated voltage DC 220V, Rated current 16A-3200A.Main power and standby power or mutual standby power change over system or city power and generator group overload switch-over. At the same time, it can operated under un-frequency on and off circuit act as disconnector.Widely used at the field of important power supply site, which transport, distribution power supply system and automatization system. For fire protection,hospital,bank,building,etc, where doesn't allow power off.

Product ProcessingAdvantage
A: It adopted double complex conact, horizontal and vertical type frame basically, It have come to "Zero" arc(No Arc Chute)

B: It adopt reliable machine interlock and electric interlock, the execu-tive union parts adopt independency overload disconnect switch, it makes more reliable and safety.C: Adopt " Zero" technique, it can force to set " Zero" under emergency situation(break off two way power supply at the same time), meet the requirement of fire protection linkage.D: Operate overload disconnect switch change over adopt singleness electromotor drive, switch over smooth and reliable, no noies, little wallop.E: Operate macnine drive motor use only under the executive overload disconnect switch change over instanecus current across, outstanding energy saying.F: Perform overload disconnect switch with mechanism interlock device, it ensure the common use, standby power working reliable and not interference.G: Distinct On and Off position indicator padlock function ect, safe realize the isolator between electric power and overload.H: High security, high automatization, high retiability, use life more than 8000 times.
