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.

Control Characteristic

27 current grades can be devided into 16A 20A 25A 32A 40A 50A 63A 80A 100A 125A 160A 200A 225A 250A 315A 350A 450A 500A 630A 800A 1000A 1250A 1600A 2000A 2500A 3200A

Basic Type:Main-standby power, self-cast, seif reset.

Type Ⅰ:100A below, city power-city power self-cast, self reset Two way power three phase short phase testing;
Above 125A, city power-city power main and standby or mutual power can do selection self-cast two way power three phase checking

Type Ⅱ: City Power-city power main and standby or mutual power supply can do selection(that is self-casting self reset or self-casting without self reset), two way power three phase and lack phase, overload voltage checking

Type Ⅲ: city power-oil machine, self casting self reset, two way power supply three phase and lack phase, overload voltage, oil machine frequency testing.
