Common installation contexts include:
What are the ratings of the S506-2.5-R?
2.5 A continuous at 250 Vac, interrupting rating 35 A at 250 Vac, 50 Hz.
Is the S506-2.5-R fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the S506-2.5-R be used on a higher fault-current circuit?
No — its interrupting rating is 35 A at 250 Vac, 50 Hz. Choose a part whose breaking capacity exceeds the prospective fault current.
