Product testing

Mechanical operation test - A pivotal assessment confirming seamless interaction of all mechanical components:

Check whether the mechanical operation of the circuit breaker is flexible, and reliable, ensuring operational dependability under varying conditions.

Test the operation functions with precision, including essential actions like closing, opening,and energy storage, guaranteeing flawless performance every time.

Electrical performance testing - A stringent process securing the electrical integrity and safety of our product:

Insulation resistance test: Employ a megohmmeter to accurately measure the insulation resistance of both main and auxiliary circuits, ensuring they meet stringent standards (typically ≥ 1M Ω).

Power frequency withstand voltage test: Administer a rated power frequency voltage (e.g., 2500V/1min) to the main and auxiliary circuits to rigorously evaluate insulation performance.

Contact resistance test: Precisely measure the contact resistance of the main contact, ensuring it remains below the specified threshold (commonly at the micro ohm level).

Protection function test - Ensures our device's superior protection capabilities:

Test the decisive action values and precise timing of protection functions, pivotal in scenarios like overload, short circuit, and ground fault situations, safeguarding your operations.

Verify the accurate settings, andfunctionality of the intelligent release device, confirming its readiness for any challenge.
