01、What products can the equipment test? What specifications are covered?
Dedicated to verification of the instantaneous trip characteristic of miniature circuit breakers (MCB); compatible with 1P/2P/3P/4P products and Type B and C trip curves, covering both single-pole and multi-pole finished products.
02、Is switching product specifications complicated? How long does it take?
Not complicated. DMC code scanning automatically loads all test parameters for the corresponding product, enabling one-click changeover without manual parameter setting, thus eliminating setting errors.
03、How is the accuracy of trip characteristic judgment ensured?
The dual critical-point verification of 1.2×In must trip and 0.8×In must not trip is used, together with ±5 ms high-accuracy timing and a standard sinusoidal-wave high-current source (tolerance ±3%), to control the threshold in both directions and avoid missed judgment at a single point.
04、What safety protections does the equipment have?
The high-voltage test area is equipped with safety door interlock, emergency stop (E-stop), and stop-on-door-opening protections, complying with electrical safety operating standards and ensuring operator safety.
05、 How are non-conforming products handled?
Four-channel defect diverting: high-ratio defective, low-ratio defective, no-current, and untestable/switch-defective are routed to separate lanes, facilitating rapid location of process problems and preventing material mix-up.
06、How is the test data traced?
Each power source is supplied with a third-party calibration certificate; DMC code scanning binds the product barcode, and test data can be uploaded to MES, realizing full-process quality traceability.
