Practical Notes
- Interrupting capability is 100 A at rated voltage, 50 Hz — confirm the circuit's prospective fault current stays below this.
- Time-delay element rides through motor starting and capacitive inrush without nuisance opening.
- Startup surges of several times rated current are tolerated for a short window.
Application Scenarios
Common installation contexts include:
- EV
- adapter
- surge
Questions and Answers
Is the SR-5H-5A-AP fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the SR-5H-5A-AP be used on a higher fault-current circuit?
No — its interrupting rating is 100 A at rated voltage, 50 Hz. Choose a part whose breaking capacity exceeds the prospective fault current.
