- Installed securely inside the panel for optimal performance
Fixed Type Installation:
The circuit breaker is affixed directly on the distribution cabinet or installation board and remains stationary.
Perfect for locations where frequent replacement or maintenance is unnecessary.
Ensures a straightforward installation process and is cost-effective.
Drawout Type Installation:
The circuit breaker is mounted on a withdrawable frame allowing for convenient maintenance, testing, and replacement.
Ideal for environments needing frequent operation or maintenance.
Though the installation is intricate and more expensive, it provides enhanced flexibility.
Plug-in Type Installation:
The circuit breaker connects to the busbar with a plug-in system, facilitating swift installation and rapid replacement.
Perfect for scenarios demanding quick replacement.
-Secondary Wiring Method
1 and 2: Connect to the intelligent controller
27 and 28:Connect to the undervoltage coil
29 and 30: Connect to the shunt coil
31 and 32:Connect to the closed coils
34 and 35: Connect to the energy storage motor
1. Rigorous Mechanical Operation Test:
Meticulously examine the mechanical operations of our circuit breaker to ensure they are smooth and unfailingly reliable.
Evaluate the seamless operation of critical functions including secure closing, precise opening, and efficient energy storage.
2. Comprehensive Electrical Performance Testing:
Insulation Resistance Validation: Deploy a high-precision megohmmeter to accurately measure the insulation resistance across both main and auxiliary circuits, ensuring strict adherence to standards (typically ≥ 1M Ω).
Power Frequency Withstand Voltage Test: Carefully apply the designated power frequency voltage (such as 2500V/1min) to both the main and auxiliary circuits, meticulously checking the integrity of insulation performance.
Contact Resistance Verification: Precisely measure the contact resistance within the main contact to confirm it remains below the predetermined threshold (usually at the micro ohm level).
3. Advanced Protection Function Test:
Thoroughly test the action values and response times of essential protection features, such as overload, short circuit, and ground fault.
Meticulously verify the parameter settings andoperational efficacy of the sophisticated intelligent release device.
Outer packaging:
Robust wooden boxes are generally employed to ensure optimal mechanical strength and protection.
These sturdy wooden crates are ideal for accommodating large circuit breakers or for the demands of international transportation.
Inner packaging:
The circuit breaker should be enveloped with cushioning materials such as foam padding, bubble wrap or pearl cotton to effectively safeguard against vibration and impacts.
For larger circuit breakers, a tiered packaging design can be utilized, allowing for the placement of accessories like manuals, tools, and spare parts) on the uppermost layer.
