The following transformers can be installed optionally in a current-terminal block :
•
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-
