This series of products belong to PC level isolated double power supply transfer switch, which is mainly used in the two neutral point grounding power supply system with AC 50Hz/60Hz, rated voltage of 400V and below, and rated working current of 1250A, to switch between power supplies due to the abnormality of one power supply, so as to ensure the reliability and safety of its power supply.
The automatic transfer switch has the positions of "common closing", "standby closing" and "two-way disconnection". It is widely used for the automatic conversion of common power supply and standby power supply of power supply systems or automatic conversion and safety isolation of two-load equipment.
The product complies with GB/T14048.11 Low voltage Switchgear and Control Equipment - Part 6-1: Multifunctional Electrical Transfer Switchgear.
