Turn on the power switch, no digital display

The leakage protector is broken

Replace the leakage protector

When the power switch is turned on, the digital display is on, but the circuit breaker cannot be closed automatically.

The motor is broken or the mechanism is stuck

The motor runs but cannot be closed

Electric operating mechanism is broken

The power indicator light flashes and the switch cannot be closed.

Abnormal power supply.

Check the three-phase four-wire voltage

Tripping immediately after closing, digital display of current value over limit

Too much leakage from the wire or load or repeated grounding of the zero wire, or the lines are mixed

Check the wire and electrical equipment

No reclosing after tripping by pressing the test button

The time between pressing the test button and the last leakage trip automatic opening is too short, causing the leakage protector to lock itself

If the circuit breaker is reclosed after a leakage trip, the test button must be pressed after the circuit breaker is closed.

Pressing the test button does not trip

The main circuit voltage is too low or the leakage circuit breaker is broken

Check the circuit or replace the leakage circuit breaker

Pressing the test button can trip the circuit breaker, but the on-site bulb test will not trip the circuit breaker.

The neutral point grounding wire of the distribution transformer is not grounded or has poor contact. The test current cannot reach the operating current value.

Check whether the neutral point grounding wire or measure the grounding resistance meets the requirements, increase the power of the test bulb or check whether the grounding is good.
