Circuit Breaker Ratings: 145KV
Power circuit breaker preferred ratings per IEEE C37.06. Covers 15.5kV through 800kV. PK = voltage class, SK = interrupting rating (kA, Number type). Fields include continuous current, close-and-latch, TRV, and interrupting time.
| voltage class | interrupting kA | close latch current kA crest (kA) | continuous current A (A) | interrupting time cycles (cycles) | rated max voltage kV (kV) | rated trv kV peak (kV) | short circuit current kA (kA) | standard |
|---|---|---|---|---|---|---|---|---|
| 145KV | 12.5 | 32.5 | 1,200 | 5 | 145 | 290 | 12.5 | IEEE C37.06-2009 |
| 145KV | 20 | 52 | 2,000 | 5 | 145 | 290 | 20 | IEEE C37.06-2009 |
| 145KV | 25 | 65 | 2,000 | 5 | 145 | 290 | 25 | IEEE C37.06-2009 |
