GDS3-100A Automatic Transfer Switch Overview
The GDS3-100A automatic transfer switch is a compact PC-class dual power transfer device designed for AC power systems requiring reliable changeover between normal and backup power sources. It is suitable for AC 50/60Hz applications and can be used in distribution panels, industrial control equipment, generator backup systems and other installations where power continuity is important.
The GDS3-100 series uses a 100A shell frame and provides rated current options from 10A to 100A. Available switching configurations include 2P, 3P and 4P, providing flexibility for different single-phase and three-phase distribution requirements.
For rated operating voltage, the series supports 2P AC230V 50Hz and 4P AC400V 50Hz configurations. The GDS3-100A automatic transfer switch has an insulation voltage of 800V, an impulse withstand voltage of 8kV, and a rated short-circuit breaking capacity of 8kA.
Its PC-class design focuses on dependable transfer switching and electrical continuity. The switch can also support remote double-break functionality with a DC12-24V EPS fire protection power supply interface, making it useful in emergency power and building distribution applications.
