Product testing

Comprehensive Mechanical Operation Test: A Thorough Examination

Dive deep into the mechanical operation of the circuit breaker, ensuring it's exceptionally flexible and steadfastly reliable, ensuring long-lasting performance.Meticulously test the seamless operation functions, including

closing ,opening , and the precision involved inenergy storage, all designed for peak efficiency. Electrical Performance Testing Excellence: A Commitment to Superior StandardsConduct an insulation resistance test with a megohmmeter, measuring the insulation resistance of both main and auxiliary circuits to ensure they exceed standard expectations (typically ≥ 1M Ω).

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

Contact Resistance Test: Carefully measure the contact resistance of the primary contact, ensuring it remains well below the specified threshold (commonly at a micro ohm level), reflecting top-tier performance.

Protection Function Test Mastery: Precision and Assurance Combined

Thoroughly evaluate the action values and timing of protection functions, which include

overload, short circuit

, and ground fault, ensuring complete reliability. Ensure the precise calibrationand optimum operability

of the state-of-the-art intelligent release device, making our product a paragon of innovation and trust.
