Ground-fault protection switchable to I

t characteristic

The ground-fault protection modules for trip units ETU745 - 776 make it possible to switch over from a constant delay time to an



t characteristic.

This provides an inverse-time tripping characteristic with a constant I

value, providing better selectivity of the ground-fault protection in

systems with several grading levels.

The setting options for the delay time remain unchanged.

Switchover to the I

characteristic can be made via:

- the t

rotary coding switch (ETU745);



this must be set to a value in the white area.

- the graphical display (ETU776)
- TD400 and the software "powerconfig"
- the COM modules with a PC with the software “powerconfig” installed
