|---|---|
| Checks the auxiliary contacts and power section IO for each | |
| Undervoltage test | Checks operation at 85% of rated voltage |
| Anti-Pumping | |
| Trip Free test | Checks tripping when trip is applied while held closed |
| Then checks closing when re-closed after trip off | |
| High-speed reclosing test | Checks operation in a close-trip-close sequence (200-300ma) |
| Chattering test | Checks operating time and chattering between main contacts (100us resolution) |
| UVT operation test | Measures closing and tripping against UVT voltage by ramping UVT up and down in steps |
| Option test | Secondary Trip Coil (dual trip) |
