Product testing

Comprehensive Mechanical Operation Test:

Diligently scrutinize the mechanical operations of the circuit breaker to ensure it is exceptionally flexible and steadfastly reliable.Test the seamless execution of operational functions such as

closing ,opening , along with the precision ofenergy storage. Electrical Performance Testing Excellence:Conduct an insulation resistance test: Utilize a state-of-the-art megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring they exceed standard requirements (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Impose rated power frequency voltage (e.g., 2500V/1min) to both main and auxiliary circuits, meticulously assessing the durability of insulation performance.

Contact Resistance Test: Precisely gauge the contact resistance of the primary contact to validate it remains below the specified threshold (commonly at the micro ohm level).

Protection Function Test Mastery:

Evaluate the action values and responsiveness timing of protection functions such as

overload, short circuit

, and ground fault. Ensure the calibrationand seamless operability

of the sophisticated intelligent release device.

 

Packaging & Shipping

Outer Packaging: A Fortress of Protection

Robust and Resilient In our pursuit of safeguarding your investment, we meticulously select wooden boxes, strategically chosen to provide unparalleled mechanical strength and durability.
