Note 1: When there are three protection requirements at the same time, the setting values cannot cross.
Note 2: Unless soecifhied in the contract, all parameters ofthe product shall be set accordinq to the factory settinqs.

Note 3: The factory setting is Ir1=1In; I2=8In: Ir3= 12iIn. Ground fault protection set to 0.5in, 0.4s mode:
Lonq delay inverse time limit factory set value t 1: 60s
The factory setting value for short delay is 0.2s.


b) The inverse time operation characteristic of the long delay overoad protection is PT =(1.5Ir1)t, . (1.05-2.0Ir) operation time is shown inthe tabie below, time error is ± 15%;
Note: t. is 1.5Ir long delay setting time; T is the actual operation time of long delay

Short delay overcurrent operation protection characteristics: The low multiple current value is the inverse time limit
When the overload current I>8Ir1, it automatically switches to a timed characteristic, as shown in the table below, timed error is ± 15%
