Engineers usually specify it for these duties:
What are the ratings of the S501-8-R?
8 A continuous at 250 Vac, interrupting rating 1,500 A at 250 Vac.
What size is the S501-8-R?
It measures 5 x 20 mm. Match the holder or clip to this footprint.
Can the S501-8-R be used on a higher fault-current circuit?
No — its interrupting rating is 1,500 A at 250 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
