Product testing

Comprehensive Mechanical Operation Test:

Conduct a meticulous examination of the circuit breaker's mechanical operation to verify its exceptional flexibility and consistent reliability.Evaluate the effortless execution of operations such as

closing ,opening , and the precise accuracy ofenergy storage mechanisms. Electrical Performance Testing Excellence:Insulation Resistance Test: Utilize a high-quality megohmmeter to assess the insulation resistance of both main and auxiliary circuits, ensuring they exceed typical standards (generally ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Apply the specified power frequency voltage (e.g., 2500V for 1 minute) to both main and auxiliary circuits to evaluate the strength and reliability of the insulation performance.

Contact Resistance Test: Precisely measure the contact resistance of the primary contact to ensure it remains below the designated threshold (often at the micro ohm level).

Protection Function Test Expertise:

Thoroughly assess the action values and timings of protection functions such as

overload, short circuit

, and ground fault. Ensure the precise calibrationand flawless operability

of the innovative intelligent release device.
