Product testing

Mechanical Operation Test:

Assess whether the mechanical operation of the circuit breaker is flexible, ensuring it is not only reliablebut also efficient.

Examine the operation functions meticulously, including closing,ensuring smooth opening,and seamless energy storagefor optimal performance.

Electrical Performance Testing:

Insulation Resistance Test: Employ a megohmmeter to accurately measure the insulation resistance of both main and auxiliary circuits, ensuring full compliance with standards (typically ≥ 1M Ω), guaranteeing safety and efficiency.

Power Frequency Withstand Voltage Test: Staff apply the rated power frequency voltage (such as 2500V/1min) to the main and auxiliary circuits, meticulously checking for superior insulation performance.

Contact Resistance Test: Precisely measure the contact resistance of the main contact to confirm it remains below the specified value (usually at the micro ohm level), ensuring uninterrupted performance.

Protection Function Test:

Evaluate the action values and timings of critical protection functions like overload, short circuit, and ground faultto ensure rapid response and protection.

Verify the precision of settings and the robustfunctionality of the sophisticated intelligent release device for enhanced safety and reliability.

 

Packaging & Shipping
