Recommended Circuit Breaker Stress Factor
| Contact Application | .. | Contact Derating Factor |
| Resistive | 0.75 | |
| Capacitive | 0.75 | |
| Inductive | 0.40 | |
| Motor | 0.20 | |
| Filament | 0.10 |
Circuit Breakers should be operated at 20C below the maximum temperature specified. Contact current is assumed to be resistive.
