Installation Instructions

- Securely installed within the panel for optimal performance

Fixed Type Installation Overview:

This installation method involves directly affixing the circuit breaker onto the distribution cabinet or an installation board , ensuring a steadfast position that

is ideal for environments where frequent replacement or maintenance is unnecessary.

Experience the advantages of a straightforward installation process combined with minimal costs.

Drawout Type Installation Explained:

The circuit breaker is mounted on a withdrawable frame, enabling effortless maintenance, streamlined testing,and efficientreplacement procedures. This method is perfect for environments that demandregular operation

or frequent maintenance tasks. Although it may involve a more complex and costly installation process, it providesenhanced adaptability and functionality.

Installation is complex and costly, but it offers greater flexibility and adaptability to various needs.Plug In Type Installation Details:

For rapid deployment, the circuit breaker connects to the busbar using a plug-in system, simplifying installation and ensuring swift changeouts.

Perfect for scenarios where quick replacement and minimal downtime are critical.

This approach is suitable for situations that necessitate immediate replacement solutions.

Secondary Wiring Methodology:Ensuring seamless connectivity with the following methods

1 and 2: Seamlessly integrate the intelligent controller
27 and 28:Effectively connect the undervoltage coil
29 and 30: Establish connection with the shunt coil
31 and 32:Secure the closed coil connections
34 and 35: Ensure robust connectivity with the energy storage motor

Product testing

Rigorous Mechanical Operation Test:

Verify the seamless mechanical functioning of the circuit breaker, ensuring it remains flexible and reliable.

Meticulously assess the operation capabilities, including closing, opening, and energy storage.

Comprehensive Electrical Performance Testing:

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

Power Frequency Withstand Voltage Test: Administer a designed power frequency voltage (e.g., 2500V/1min) to the main and auxiliary circuits to rigorously assess insulation integrity.

Contact Resistance Test: Accurately measure the contact resistance of the primary contact to confirm it remains below specified threshold values (typically at micro-ohm levels).

Advanced Protection Function Test:

Evaluate the precise action thresholds and timing of protection features, including overload, short circuit, and ground fault.

Confirm the settings andefficacy of the intelligent release mechanism.

 

Packaging & Shipping

Outer packaging:

We utilize robust wooden boxes to ensure exceptional mechanical strength and durability.

This wooden crate design is perfect for large circuit breakers and suited for international transportation needs.

Inner packaging:

The circuit breaker is carefully enveloped using protective buffer materials such as foam pads, bubble films or pearl cotton to effectively minimize vibration and prevent any potential collisions.

For larger circuit breakers, our packaging solution includes a sophisticated layered design, where essential accessories like manuals, tools, and spare partsare thoughtfully organized on the upper layer to ensure easy access.
