1.5The circuit breaker should be installed in a dry, ventilated, dust-free, and free of harmful gases, away from magnetic fields and vibration. It should be vertically fixed on the distribution box or wall for easy operation.

2.Usage

2.1 Power transmission

Set the power switch of the circuit breaker to the "ON" position, the power indicator light will turn on, and the "Trip" indicator light will start flashing (indicating a closed waiting state). The electric closing mechanism of the circuit breaker will operate. When the circuit breaker is closed properly, it will be in the normal closed state, and the "Trip" indicator light will turn off.

2.2 close electricity

Set the circuit breaker [power switch] to the [off] position, trip the circuit breaker, and turn off the main circuit.

2.3Leakage over limit tripping test:

Press the 'Test' button, the circuit breaker should be able to trip, the 'Leakage Fault' indicator light should be on, the 'Trip' indicator light should be on, and the circuit breaker should be able to trip5In seconds, the 'trip' indicator light starts flashing (the electric closing mechanism is running and waiting for closing), indicating that the electric closing mechanism is in a closed state20～60The automatic closing is completed in seconds. After the closing is in place, the trip indicator light and leakage fault indicator light will turn off.

2.4 Setting of leakage action value:

Manual adjustment and automatic adjustment can be selected as needed

According to the magnitude of the leakage current in the circuit, the leakage action value range of the circuit breaker can be manually set, or the leakage action value can be automatically set to levels I, II, III, and IV. According to different specifications,The leakage current of each gear corresponds to: Grade I:75mA Grade II:150mA Grade III:300mAGrade IV:500mAperhaps1000mA.

Press the 【 Set 】 key to set the gear, and press the 【 Set 】 key continuously to set the gearLevel I → Level II → Level III →Grade IV→ Class III cycle conversion; Press and holdPress the 'Settings' button for 3 seconds to enter automatic gear setting.(When)The gear indicator light is always on for a certain gear, indicating a manually set fixed gear. When the gear indicator light flashes, it indicates an automatic gear. If the circuit breaker has a gear memory function after shutting down and turning on after a power outage when in a fixed gear, the gear will remain unchanged from the original gear; If it is in automatic mode, the circuit breaker will automatically set the gear according to the leakage of the line after shutting down and turning on after power failure.

2.5This circuit breaker cannot automatically close due to overload or short circuit tripping. The power switch of the circuit breaker needs to be turned off and reconnected before power can be restored.

2.6 The auxiliary power supply used in the internal electronic circuit of this circuit breaker isNPile and5Pile, if used for three-phase power protection or specifically for single-phase protection,NThe pile must be connected to the neutral wire,5The pile must be connected to the phase line, otherwise it cannot be powered on or manually closed without leakage protection.

2.7Press and hold the [Alarm] button when power outages are not allowed or when power must be supplied due to line leakage faults during maintenance5In seconds, the alarm function is activated, and the 'Alarm Start' light is on. At this time, only the 'Leakage Fault' indicator light is on when the leakage exceeds the limit, without tripping. The use of this feature must be approved by the local power department. After entering the alarm state, press and hold the [Alarm] button again to approximately5Restore the leakage tripping function in seconds.

2.8The opening and closing indicator block is used to indicate the opening and closing status of the circuit breaker.

2.9 When the leakage tripping does not require automatic reclosing function or the internal closing motor is damaged, manual closing can be used, and a straight screwdriver can be used to press it in orderTurn the device clockwise to the closed position and stop (when the indicator block is "closed"). If manual opening is required, turn the device clockwise again to the open position and stop. If manual closing is required again, the "opening and closing switch" of the protector must be opened and closed again, and then the device must be turned clockwise to the closing state before stopping.

2.11When the circuit breaker trips, the digital display will flash to show fault information

aLeakage fault tripping

Display fault current and tripping phase alternately, whileThe leakage fault and trip indicator lights are on.

Example: If L345 → - AA - is displayed, it indicates that this trip is a leakage trip, with a fault current of 345mA and A-phase leakage. If - Cd - is displayed, it indicates a surge leakage trip.

bUnder overvoltage tripping

Trip display -9Y - indicates undervoltage tripping, and the 'Trip Indicator' light is on at the same time. After the power supply voltage returns to normal, the circuit breaker automatically closes and supplies power.

cLoad control tripping

The digital display flashes and alternately displays the current values of each phase load before tripping, while the 'overcurrent fault' and 'trip indicator' lights are on.
