NOTE
You can read the type of the current transformer used on the side of the terminal block, for example 3xI
1xIE. The reference number is located on the connector interface and can only be read when removed.

Current-Terminal Block for Non-Modular Devices (7xx81, 7xx82)
The following transformers can be installed optionally in a current-terminal block for non-modular devices:
•
4 protection-class current transformers
•
3 protection-class current transformers and 1 instrument transformer
Protection-class current transformers on non-modular devices are transformers with a rated current of 1 A or
5 A and a measuring range of 50 x rated current.
Instrument transformers are transformers with a rated current of 1 A or 5 A and a measuring range of
1.6 x rated current. Instrument transformers are also referred to as sensitive protection-class current trans-
formers or sensitive ground-current transformers.
