| 28-day test |
| Test program | The sample is supplied with AC 30V and rated current, the power-on
time is 21 hours, the power-off time is 3 hours, and the cycle is
28 times. The terminal temperature is measured during the last
power-on cycle, and compared with the initial measured temperature,
the temperature rise value is compared with the standard
requirements. After the temperature rise measurement, the current
rises to the tripping current value in 5 seconds, and the circuit
breaker should trip within the given/preset time. |
| Output voltage | Not less than AC30V, adjustable |
| Output AC current | AC 0.5-125A |

| Number of cycles | 0-9999 times can be preset |
| Tripping time | recordable |
| Tripping current | 1.0~200A |
| Evaluation of results | 1. Whether the circuit breaker tripped during the test or not. If
it tripped, it failed; if it did not trip, it passed. 2. Temperature rise comparison, if it exceeds the standard value by
15K, it is defective; if it does not exceed the standard value, it
is acceptable. 3. After the current rises to the tripping current, if it trips
within the given/preset time, it is acceptable; if it exceeds the
given/preset time or does not trip, it is defective. |
