The Switch is mainly used for testing whether normal or spare power is normal or not. When the normal power is abnormal,
the spare power works at once, which therefore ensure the continuity, reliability, and safety of power supply.
The product is specifically designed for household orbit-type installation and specifically used in Din-Rail power distribution box.
STQ3-100 Series automatic transfer switch is suitable for the emergency power supply system with 50 or 60Hz alternating current
rated 400v, 100A.
It is compact in structure, reliable in transfer in transfer, convenient in installation and maintenance, and has long life expectancy.
Widely used in various occasions where continuous power failure is not allowed, it can be operated both electrically and manually.
STQ3-100 Series automatic transfer switch complies with requirements of Low-Voltage switch gear and control gear specified
by IEC 60947-6-1.
