Installation Instructions

-Installed inside the panel

Fixed Type Installation:

The circuit breaker is steadfastly secured onto the distribution cabinet or installation board ensuring absolute immobility once placed.

This method is impeccable for applications where frequent switching or ongoing maintenance is unnecessary.

Enjoy a hassle-free installation and a budget-friendly setup.

Drawout type installation:

Here, the circuit breaker is mounted on a withdrawable frame, catering to convenient maintenance,allowing for testing,and component replacement with ease.

This setup is ideal for environments necessitating frequent operation or regular servicing.

While installation is intricate and comes with higher costs, it delivers superior adaptability and flexibility.

Plug in type installation:

Utilizing a seamless plug-in mechanism, the circuit breaker attaches directly to the busbar, enabling swift installation and immediate replacement.

This approach is ideal for situations requiring rapid component exchange.

-Secondary wiring method

1 and 2: Seamlessly connect the intelligent controller
27 and 28:Efficiently link the undervoltage coil
29 and 30: Securely attach the shunt coil
31 and 32:Firmly anchor the closed coils
34 and 35: Reliably connect the energy storage motor

Product testing

Mechanical operation test: Ensure peak performance and longevity with our thorough mechanical operation evaluations.

Check whether the mechanical operation of the circuit breaker is flexible and reliable.

Test the operation functions such as closing, opening, and energy storage.

Electrical performance testing: Experience assurance with our rigorous electrical performance examinations.

Insulation resistance test: Utilize a high-precision megohmmeter to gauge the insulation resistance of both main and auxiliary circuits, guaranteeing compliance with industry standards (typically ≥ 1M Ω).

Power frequency withstand voltage test: Administer the rated power frequency voltage (for instance, 2500V/1min) on the main and auxiliary circuits to meticulously assess insulation performance.

Contact resistance test: Meticulously measure the contact resistance of the main contact to ensure it remains below the designated threshold (commonly at the micro ohm level), ensuring unparalleled performance.

Protection function test: Safeguard with precision through our dedicated protection function assessments.

Test the action values and time of protection functions such as overload, short circuit, and ground fault.

Verify the settings andfunctionality of the intelligent release device, ensuring they meet all specifications with exceptional precision.
