Product testing

Mechanical Operation Excellence Test:

Ensure the mechanical operation of the circuit breaker is incredibly flexible and unfailingly reliable.

Assess the seamless execution of operations such as secure closing, swift opening, and efficient energy storage.

Rigorous Electrical Performance Testing:

Insulation Resistance Assurance: Employ a megohmmeter to precisely measure the insulation resistance of both main and auxiliary circuits, confirming they surpass the standard threshold (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Evaluation: Administer rated power frequency voltage (such as 2500V for 1 minute) to both main and auxiliary circuits to verify exceptional insulation performance.

Contact Resistance Precision Test: Assess the contact resistance of the main contact to guarantee it remains below the designated micro ohm level.

Robust Protection Function Testing:

Evaluate the precise action values and response times of protection functions including overload, short circuit, and ground fault.

Confirm the accuracy of settings andthe flawless functionality of the sophisticated intelligent release device.
