Performance Characteristics

1) Time: Inherent opening and closing times for all 12 circuit breakers, including phase-to-phase and phase-to-phase synchronization.

2) Reclosing: Closing-opening, opening-closing, and opening-closing-opening processes for each circuit breaker: first opening time, first closing time, second closing time, short-term closing time, and no-current time.

3) Bounce: Closing bounce time, number of bounces, bounce process, and bounce waveform for each circuit breaker; opening bounce amplitude for each circuit breaker.

4) Speed: Initial opening and closing speeds, maximum speed, and time-stroke characteristic curve.

5) Stroke: Total stroke, opening distance, overtravel, overshoot stroke, and bounce amplitude.

6) Current: Opening and closing current values and waveforms for the opening and closing coils. 7) Operating voltage: The machine provides a DC 0～300V/20A digitally adjustable circuit breaker operating power supply, automatically completes the low voltage operating test of the circuit breaker, and measures the operating voltage value of the circuit breaker.
