Ideal for environments where frequent replacement or maintenance is not necessary.

This method ensures ease of installation and cost-efficiency.

Drawout Type Installation:

The circuit breaker is mounted on a removable frame providing convenient maintenance, testing, and replacement options.

Perfect for settings that demand regular operation or upkeep..

Though the installation process may be intricate and costly, it provides enhanced flexibility..

Plug-in Type Installation:

The circuit breaker connects seamlessly to the busbar via plug-in connections, facilitating swift installations and replacements.

Best suited for scenarios necessitating rapid replacements.

-Secondary Wiring Method

Connections 1 and 2: Link the intelligent controller
Connections 27 and 28:Link the undervoltage coil
Connections 29 and 30: Link the shunt coil
Connections 31 and 32:Link closed coils
Connections 34 and 35: Link the energy storage motor

Product testing

Rigorous Mechanical Operation Test:

Meticulously check to ensure that the mechanical operations of the circuit breaker are exceptionally smooth and highly dependable.

Thoroughly test the crucial operation functions, including precise closing, swift opening, and robust energy storage.

Comprehensive Electrical Performance Testing:

Insulation Resistance Test: Employ a megohmmeter to meticulously measure the insulation resistance across both main and auxiliary circuits, ensuring they adhere to the stringent standard (usually ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Administer the rated power frequency voltage (such as 2500V/1min) to both the main and auxiliary circuits, meticulously checking the insulation performance.

Contact Resistance Test: Accurately measure the contact resistance of the main contact, ensuring it remains below the prescribed value (usually at the micro ohm level).

Advanced Protection Function Test:

Conduct thorough testing on the action values and timing of protection functions such as overload, short circuit, and ground fault.

Diligently verify the precision of settings andefficiency of the state-of-the-art intelligent release device.

 

Packaging & Shipping

Outer Packaging:

We ensure resilience with sturdy wooden boxes that are specifically crafted to offer exceptional mechanical strength.

Our wooden crates are expertly designed for accommodating large circuit breakers and are perfect for international transportation.
