Dual Power Switch(CB Grade) 125A 250A 630A

This series of Dual Power Automatic Transfer Switches features an electromechanical integrated design, with accurate and reliable switching performance, excellent electromagnetic compatibility, strong anti-interference capability and high automation level. This product can not only switch between two power supplies, but also detect the voltages of two three-phase four-wire systems simultaneously. When any phase voltage is abnormal, it can automatically switch to the normal power supply. The intelligent dual power automatic transfer system is suitable for dual power supply systems with AC 50/60Hz, rated operating voltage of 400V and rated operating current up to 630A. It can realize automatic switching between Power Source Ⅰ (N) and Power Source Ⅱ (R) (and can also be used for manual switching). This product is widely applied to the power transmission and distribution systems as well as automation systems in critical power supply locations where power interruption is prohibited, includ…
