Change-over and Transfer Switches

The TKDQ series of automatic transfer switch is used in the dual power supply system with the rated frequency of 50Hz or 60 Hz, the rated working voltage 220V or 400V, and the rated current up to 800A for the switching between common power supply and standby power supply. It can provide bottom loads and cables with short circuit and overload protection. It is often applied in the low voltage terminal distribution systems in the civilian area, industrial area, construction field, and other fields.
