Offers straightforward installation and cost-effectiveness.

Drawout Type Installation:

The circuit breaker is effortlessly installed on a withdrawable frame, enhancing ease of maintenance,facilitating testing, and simple replacement.

Perfect for applications that demand frequent operation or regular maintenance,offering unparalleled adaptability.

Complex and higher in cost, but it provides enhanced flexibility and versatility..

Plug-In Type Installation:

The circuit breaker seamlessly connects to the busbar through a plug-in method, making installation and rapid replacement effortlessly simple.

Perfectly suited for environments requiring swift and efficient replacements.

-Secondary Wiring Method

1 and 2: Connects to the intelligent controller for optimal control.
27 and 28:Links to the undervoltage coil for safe operation.
29 and 30: Connects to the shunt coil for enhanced functionality.
31 and 32:Connect to closed coils for secure closure.
34 and 35: Connect to the energy storage motor, optimizing energy efficiency.

Product testing

1. Mechanical Operation Test:

Ensure the seamless and flawless mechanical operation of the circuit breaker, confirming it is remarkably flexible and unfailingly reliable.

Evaluate and test the core operational functions including precise closing, smooth opening,and efficient energy storage,ensuring optimal performance.

2. Electrical Performance Testing:

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

Perform a Power Frequency Withstand Voltage Test: Apply the designated power frequency voltage (e.g., 2500V for 1 minute) to assess the insulation integrity of the main and auxiliary circuits.

Execute a Contact Resistance Test: Measure the contact resistance of the main contact to confirm it remains beneath the stipulated threshold (typically in the micro ohm range).

3. Protection Function Test:

Diligently test the precise action values and timing of critical protection functions, including overload, short circuit protection, and ground fault detection,to ensure maximum safety.

Authenticate and verify the settings andfunctionality of the intelligent release device, guaranteeing state-of-the-art protection capabilities.

 

Packaging & Shipping

Outer packaging:

Robust wooden boxes are typically utilized to ensure remarkable mechanical strength.

Designed for enduring large circuit breakers and international shipping, the wooden crate provides unmatched protection and resilience.

Inner packaging:

Delicately wrap the circuit breaker using superior cushioning materials such as foam pads, bubble film or pearl cotton to effectively guard against vibrations and impacts.

For larger circuit breaker models, a strategic layered box design may be employed, with accessories (including manuals, tools, spare parts) neatly organized on the upper tier to maximize convenience and accessibility.
