6.5 NOMINAL CURRENT

SETTING FOR LPCT

LPCT amperometric phase inputs

Factory default settings:

• Primary nominal phase current

: 300 A

• Nominal residual current

: 1 A as shown in the previous pages)

To modify the phase rated currents, the dip-switches placed on the rear panel must be set.

[1]

Note 1 For LPCT versions the dip-switch position, located inside the CPU board, concerning the phase 1 A or 5 A current setting are irrelevant
