Installation Instructions

-Securely installed inside the panel for optimal stability

Fixed Type Installation:

The circuit breaker is steadfastly fixed on the distribution cabinet or installation board, rendering it immovable.

It is ideal for scenarios that do not necessitate frequent replacement or maintenance, offering enduring performance.

This ensures easy installation and minimizes costs, making it a cost-effective solution.

Drawout type installation:

The circuit breaker is adeptly installed on a withdrawable frame to facilitate convenient maintenance, efficient testing, and swift replacement,ensuring maximum utility.

This type is perfect for environments demanding frequent operation or routine maintenance,providing adaptability.

While the installation process is intricate and costs may be higher, it offers enhanced flexibilityto meet dynamic needs.

Plug in type installation:

The circuit breaker conveniently connects to the busbar with a plug-in connection, allowing for rapid installation and swift replacement.

This is suitable for environments requiring quick and efficient replacement solutions.

-Secondary wiring method

1 and 2: Integrate the intelligent controller
27 and 28:Link the undervoltage coil
29 and 30: Connect the shunt coil for seamless operation
31 and 32:Attach closed coils
34 and 35: Securely connect the energy storage motor for reliable performance

Product testing

Mechanical operation test:

Ensure the circuit breaker's mechanical operations are impeccably flexible and reliable.

Meticulously assess operational functionalities such as closing, opening, and energy storage.

Electrical performance testing:

Insulation resistance test: Utilize a megohmmeter to meticulously measure the insulation resistance of both main and auxiliary circuits, ensuring compliance with standards (typically ≥ 1M Ω).

Power frequency withstand voltage test: Administer rated power frequency voltage (such as 2500V/1min) to the main and auxiliary circuits, ensuring robust insulation performance.

Contact resistance test: Precisely measure the main contact's resistance, guaranteeing it remains within specified parameters (commonly at micro ohm levels).

Protection function test:

Scrutinize the activation values and response times for protection functions, including overload, short circuit, and ground fault.

Authenticate the settings andfunctionality of the sophisticated intelligent release device.

 

Packaging & Shipping

Outer Packaging Excellence:

Robust Strength with Durable Wooden Boxes are strategically chosen to ensure unparalleled mechanical strength and reliability.

Our expertly crafted wooden crates are ideal for accommodating large circuit breakers or for international transport.

Inner Packaging Precision:

Securely envelop the circuit breaker in protective buffer materials such as foam pads, bubble film or pearl cotton, ensuring optimal protection against vibration and collision.

For larger circuit breakers, our packaging box may feature a sophisticated layered design, with essential accessories (including manuals, tools, and spare parts) neatly organized on the upper layer for easy access.

Our advanced production line is dedicated to excellence.
