Phase over voltage protection 4p

● Features a single-phase line break occurred when the line under-voltage, single-phase line voltage returns to normal after a reset automatically switched by the delay line, without manual operation. 2 lines or transient overvoltage transients occur, the protection does not malfunction. Three lines due to inaccurate contact voltage instability and other failures occur, or when a sudden power failure suddenly calls, protection does not pick up the line. 4 line fault voltage is the highest, the protector itself will not be damaged.
