Establishing of the Selection parameter according to IEC /DIN EN 61439-1 attachment C

The following table shows the default values of the mobile distributors manufactured by INDU-ELECTRIC. According to the above-mentioned standard, agreements must be made between the user and the manufacturer when making an offer, if deviations from the stated INDU-ELECTRIC standard values are required by the customer.

According to DIN 61439-1, the user must define the following functions and features
