Electrical Characteristics:
The document provides details on rated current (In), conventional time, conventional current, non-fusing current, and fusing current. For currents In ≤ 63A, the conventional time is 1 hour with a non-fusing current of 1.25In and a fusing current of 1.6In. For currents 63A < In ≤ 160A, the conventional time is 2 hours.

Graphical Data:
An average I-T characteristics curve is provided for reference, showing the relationship between current (A) and time (s) for different current ratings (40A, 50A, 63A, 80A, 100A).
