Selection Notes
- Interrupting capability is 1000 A @ 72 Vdc; 500 A @ 80 Vdc — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 72 Vdc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 70 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- battery
- EV
- transformer
Part Number and Packing

Q&A
What are the ratings of the 2822HC70-R?
70 A continuous at 72 Vdc, interrupting rating 1000 A @ 72 Vdc; 500 A @ 80 Vdc.
Can the 2822HC70-R be used on a higher fault-current circuit?
No — its interrupting rating is 1000 A @ 72 Vdc; 500 A @ 80 Vdc. Choose a part whose breaking capacity exceeds the prospective fault current.
