Current-Terminal Block of the Modular Devices
The following transformers can optionally be installed in a current-terminal block for modular devices:
•
4 protection-class current transformers
•
3 protection-class current transformers and 1 instrument transformer
•
4 instrument transformers
Protection-class current transformers on modular devices are transformers with a rated current of 1 A or 5 A
and a device-dependent measuring range of 20 x rated current or 100 x rated current.

NOTE
You can read the type of the current transformer used on the side of the terminal block:
•
C73334A 1A18 *7* = 4 protection-class current transformers
•
C73334A 1A18 *8* = 3 protection-class current transformers and 1 instrument transformer
•
C73334A 1A18 *9* = 4 instrument transformers
