## Ratings 

- 1: Not mentioned in ISO standards 

- 2: Short Circuit Protector only 

- 3: 0298xxx.ZXB has white font color on all ratings. 

- 4: Voltage Drop measurements for short circuit protectors taken at 75% of rated current. 

The typical I[2] t is an average value calculated from the breaking capacity tests by using the melting time before the arcing occurs.
