Feature: 1. Overvoltage and undervoltage protector (OUPA) with automatic reclosing function is an intelligent protector that integrates overvoltage protector and undervoltage protector together. 2. In the event of an over‑capacity or under‑voltage failure on a single‑phase line, the product can be cut off and the connection can be automatically resumed for a period of time after the line capacity has restore to its normal state. 3. The over‑voltage and under‑voltage values of the products can be set by you, and can be adjusted according to the actual local situation. 4. Over‑voltage protection value range of 230V‑300V (default: 270V). 5. Under‑voltage protection value range of 140V‑210V (default: 170V).
