Features

Unique Advantage

• Timing:All 12 common breakers have synchronized opening and closing times, with similar phase characteristics.
• Reclosing:Each breaker’s closing-opening and opening-closing cycles are measured, including one opening time, one closing time, two opening times, short-circuit duration, and current interruption values.
• Bounce:This includes the closing bounce time, number of bounces, bounce process details, and bounce waveform for each breaker, as well as the rebound amplitude during opening.
• Speed:This covers the opening and closing speeds, maximum speed, and the time-travel characteristic curve.
• Current:This includes the opening and closing current values and the current waveforms for the opening and closing coils.
• Action Voltage:The machine provides a digital adjustable power supply (DC 30-250V/20A) for testing. It automatically performs low-voltage action tests and measures the action voltage values for each breaker.
