Engineers usually specify it for these duties:
What are the ratings of the MDL-2-1/4-R?
2.25 A continuous at 250 Vac, interrupting rating 100 A at 250 Vac; 10,000 A at 125 Vac.
Is the MDL-2-1/4-R fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the MDL-2-1/4-R be used on a higher fault-current circuit?
No — its interrupting rating is 100 A at 250 Vac; 10,000 A at 125 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
