Effortless installation and economical setup.

Drawout Type Installation:

The circuit breaker is mounted on a withdrawable frame, facilitating easy maintenance, testing, and component replacement.

An ideal choice for settings necessitating frequent operation or servicing.

Though installation is more complex and involves higher costs, it offers superior adaptability.

Plug-in Type Installation:

The circuit breaker integrates seamlessly with the busbar through a plug-in mechanism, promising rapid installation and quick replacement.

This technique is tailored for scenarios necessitating swift replacement.

-Secondary Wiring Method

1 and 2: Integrate the intelligent controller seamlessly
27 and 28:Connect the undervoltage coil with precision
29 and 30: Securely connect the shunt coil
31 and 32:Anchor the closed coils with stability
34 and 35: Connect the energy storage motor with reliability

Product testing

Mechanical operation test:

Ensure that the circuit breaker's mechanical operations are conducted with the utmost flexibility and reliability. This involves a meticulous examination to ascertain smooth and dependable performance.

Thoroughly test all operational functions, including closing, opening, and energy storage. Each of these vital functions must demonstrate impeccable efficacy and safety.

Electrical performance testing:

Conduct an insulation resistance test using a megohmmeter. Measure the insulation resistance of both main and auxiliary circuits to ensure they meet industry standards (typically ≥ 1M Ω), ensuring enhanced safety and functionality.

Power frequency withstand voltage test: Apply the specified rated power frequency voltage, such as 2500V for 1 minute, to both main and auxiliary circuits. This is crucial to evaluate the robust insulation performance that safeguards the circuit's integrity.

Contact resistance test: Precisely measure the contact resistance of the main contacts. It is imperative that the resistance remains below the specified threshold (usually at the micro-ohm level) to maintain seamless electrical connection and efficiency.

Protection function test:

Rigorous testing of protection functions is essential. Examine the action values and response times for critical protections like overload, short circuit, and ground fault. These measures ensure the circuit breaker's ability to swiftly and effectively manage electrical anomalies.

Verify and validate the settings andfunctionality of the intelligent release device, guaranteeing state-of-the-art protection and operational precision.
