Dedicated testing device that integrates contact action recording, current waveform recording, and variable power supply.
The circuit breaker/disconnector testing device "TA-300A" is a dedicated testing device that integrates contact operation recording, current waveform recording, and a variable power supply. With this single device, you can conduct opening and closing characteristic tests of circuit breakers/disconnectors in accordance with JEC-2300 and 2310. Thanks to the touch panel display and operation command output buttons, the device is easy to operate even for first-time users, and test results can be quickly confirmed on the screen and printed out. It is a standard device that allows for safe and efficient opening and closing characteristic tests during the completion and regular inspections of circuit breakers and disconnectors. 【Features】 ○ Easy operation pursued with an outdoor-specific touch panel ○ Built-in induced voltage removal circuit ○ Measurement of pre-insertion time for resistive contacts is possible ○ Automatic confirmation of pumping prevention is possible ○ Phase loss testing is possible For more details, please contact us or download the catalog.
