Product testing

1. Mechanical Operation Test:

Carefully check whether the mechanical operation of the circuit breaker is perfectly flexible and unfailingly reliable. This ensures smooth functionality.

2. Test all crucial operation functions, such as seamless closing, precise opening, and efficient energy storage. Every function is vital for performance.

3. Electrical Performance Testing:

Insulation Resistance Test: Employ a high-quality megohmmeter to rigorously measure the insulation resistance of both the main and auxiliary circuits, ensuring they surpass industry standards (typically ≥ 1M Ω).

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

Contact Resistance Test: Accurately measure the contact resistance of the main contact to ensure it remains well below the specified threshold (commonly at a micro ohm level).

4. Protection Function Test:

Test the action values and response times of vital protection functions such as overload, short circuit, and ground fault. These tests are crucial for operational safety.

Carefully verify the precise settings andoptimal functionality of the intelligent release device, ensuring top-tier performance and safety.
