Main technical parameters
Remarks on default values of project technical parameters
Display LCD cyclic display of three-phase voltage, three-phase current, and leakage current values
Leakage function rated residual operating current leakage operating time This five speed delay type is 0.06s100, 200, 300, 500, 800mA. All specifications of circuit breakers can be set to 500mA. The operating current is 75% ± 5% of the set current
The reclosing time can be set between 20-60s
Automatically set to the maximum value when turned on, and after 10 minutes, automatically downshift. The actual leakage value of the set gear is less than 50% of the set value. Namely, when the actual leakage current is 0-50mA, it is set to 100 levels; when it is 50-100mA, it is set to 200 levels; and when it is 100-150mA, it is set to 300 levels.
When the automatic tracking is set to 150-250mA, it is set to 500 gear, and when it is greater than 250mA, it is set to 800 gear. Up grading users can activate it themselves
lose
When the leakage current reaches the trip value of this gear, the circuit breaker trips, then automatically recloses, and automatically shifts up to the highest gear; If the leakage value is still greater than the highest gear trip
When the value is reached, it will lock after being released and will no longer reclose
When tripped due to leakage, it will automatically close, such as within 3 minutes
If the automatic reclosing trips once, it will lock and no longer reclose. If it takes more than 3 minutes, it will trip
Reset the timer and reclose
The leakage mutation setting values are 25, 50, 75, and 100mA. The leakage mutation can be set to open or close 50mA. When the leakage value suddenly increases beyond the set value, the circuit breaker will trip
The alarm does not trip due to excessive leakage. The alarm can be set to turn on or off, and users can turn it on themselves
240-300V can be set to 275V ± 5V
Overvoltage recovery voltage is less than the set voltage of 10V
The overvoltage function can be set to turn on or off
Overvoltage tripping and closing delay (1-99s) can be set to 10s when a voltage fault (overvoltage, undervoltage, phase failure) occurs
The voltage of 160-200V can be set to 165 ± 5V with digital flashing. After a delay, it will trip and automatically close after returning to normal without locking. Users can turn off the voltage protection function by themselves
