Installation Instructions

-Installed inside the panel

Fixed Type Installation:

Ensure the circuit breaker is steadfastly secured onto the distribution cabinet or installation board where it remains perfectly stationary.

This method is optimum for scenarios where replacements or upkeep are rarely required.

Experience the advantage of straightforward installation and economical cost efficiency.

Drawout Type Installation:

The circuit breaker is expertly placed on a withdrawable frame that is meticulously engineered for hassle-free maintenance, seamless testing, and effortless replacement.

Ideal for environments necessitating frequent operation or routine maintenance.

Although installation can be intricate and expensive, it offers superior adaptability.

Plug-in Type Installation:

The circuit breaker connects seamlessly to the busbar through a plug-in connection, guaranteeing quick installation and swift replacement.

Excellent for settings where rapid exchanges are crucial.

-Secondary Wiring Method

1 and 2: Interface the intelligent controller seamlessly
27 and 28:Connect efficiently to the undervoltage coil
29 and 30: Integrate the shunt coil effectively
31 and 32:Engage closed coils with precision
34 and 35: Connect the energy-storing motor with ease

Product testing

Comprehensive Mechanical Operation Test:

Engage in a meticulous examination of the circuit breaker's mechanical operations, ensuring it operates with supreme flexibility and unwavering dependability.Conduct an evaluation of its seamless operational capabilities, including

closing ,opening , and the preciseenergy storage functionality. Electrical Performance Testing Excellence:Perform a comprehensive insulation resistance test: Utilize a megohmmeter to meticulously measure the insulation resistance of both main and auxiliary circuits, ensuring they not only meet but exceed standard requirements (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Deploy a rated power frequency voltage (e.g., 2500V/1min) to both the main and auxiliary circuits to rigorously test the sturdiness of insulation performance.

Contact Resistance Test: Carefully assess the contact resistance of the primary contact to ascertain it remains well below the established threshold (commonly at a micro ohm level).

Protection Function Test Mastery:

Thoroughly evaluate the activation values and timing of vital protection functions, including

overload, short circuit

, and ground fault conditions. Ensure the precise calibrationand flawless operability

of the advanced intelligent release device.

 

Packaging & Shipping

Outer Packaging: A Fortress of Protection

Robust and Resilient Wooden boxes are strategically selected to offer unparalleled mechanical strength.

Wooden crates are ideal for accommodating large circuit breakers, perfectly tailored for international transportation.

Inner Packaging: Cushioned Care

Envelop the circuit breaker in layers of protective materials such as foam pads, bubble film or pearl cotton to mitigate the risks of vibration and collision.

For larger circuit breakers, the packaging box can feature a sophisticated layered design, with essential accessories like manuals, tools, and spare partsthoughtfully placed on the upper layer to enhance accessibility.
