2. performance
2.1. time
The machine can measure the inherent opening and closing time of 12 way metal fracture, the same
phase and the same period time. It can measure the short time and no current time of closing opening,
opening closing and opening closing opening process, the closing bounce time, and the pre switching time
of closing resistance for some models.
2.2. speed and stroke
This machine can record and measure the closing bounce time, bounce times, bounce process and bounce
waveform of each fracture.
2.3. speed and stroke
The machine can record and calculate the rigid opening and closing speed, maximum speed,
average speed, total stroke, opening distance, overtravel, rebound amplitude and time stroke characteristic curve.
2.4. current and voltage
This machine can record the opening / closing current value and current waveform of the opening / closing coil.
It can provide dc5 ~ 270V / 10A (20a) digital adjustable circuit breaker action power supply. It can automatically
complete the low voltage action test of the circuit breaker and measure the action voltage value of the circuit breaker.
2.5. closing resistance
Some models of this machine can measure 6-way closing resistance values and their pre switching time at the same time.
