By selecting the appropriate value and confirming it with the OK key, the parameterisation is
entered in the factory setting. Once the s
etting has been made, the value of the parameter
automatically returns to 0. The setting is only remains permanently valid if parameter P550 =1 is
set (transfer of the values from the RAM to the flash memory)
0 = No change: Does not change the parameterisation.
1 = Load factory setting: The complete parameterisation of the motor starter reverts
to the factory setting.

The I

t motor shut-down class determine
s how quickly the motor starter switches off in case of
excess current. The motor shut-
down classes are oriented to curves which are defined in EN
60947-4-2. Three different classes can be selected. The rated motor current on which the I

t
monitoring is based is determined by P203. Above 7.2 x the rated motor current, switch-
off is
practically instantaneous.
0 = Class 10A, 1.5 x overcurrent for 120sec
1 = Class 10, 1.5 x overcurrent for 240sec
2 = Class 20, 1.5 x overcurrent for 360sec
ATTENTION
The motor I2t circuit breaker cannot replace protection with an external fuse against short circuit
or a short to earth!
