Product testing

Mechanical Operation Test: Guaranteeing Seamless Functionality

Conduct a thorough examination of the circuit breaker's mechanical operation to certify it is flexible, robust, andunfailingly reliable.

Meticulously verify the operational capabilities, including the crucial actions of: closing, opening,and energy storage.

Electrical Performance Testing: Prioritizing Unmatched Safety

Insulation Resistance Test: Utilize a megohmmeter to meticulously measure the insulation resistance in both main and auxiliary circuits, ensuring it meets and exceeds industry benchmarks (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Administer the rated power frequency voltage (e.g., 2500V for 1 minute) across both main and auxiliary circuits to evaluate their superior insulation capabilities.

Contact Resistance Test: Precisely gauge the contact resistance of the primary contact to ensure it remains below the designated threshold (commonly at the micro-ohm level), confirming optimal connectivity.

Protection Function Test: Unwavering Protection for Your Equipment

Assess the precision of action values and timing of protection functions, with a focus on overload, short circuit, and ground fault scenarios.

Meticulously validate the settings andoperational effectiveness of the intelligent release device, ensuring it delivers unrivaled performance.
