三相 63A 自复式过欠压保护器 Three phase 63A self-reset over voltage and under voltage protective device 产品描述 Description The self-reset over voltage and under voltage protective device considered modular design. The circuit board adopted good quality Latching relays and others components with reliable performance. When the power supply is unstable (voltage is too high or too low), the protection function will be activated automatically. Once the voltage exceeds the limited range, it will be cut off automatically, so that to protect the peoples and electrical appliances /equipment in safe, also the protective device will be reset by itself in 60 seconds, when t
