Installation Instructions

-Installed inside the panel

Fixed Type Installation:

The circuit breaker is seamlessly secured onto the distribution cabinet or installation board ensuring a stable, immovable setup.

Ideal for environments where frequent replacement or maintenance is unnecessary, offering reliability and stability.

Effortless installation and at a minimal cost.

Drawout Type Installation:

The circuit breaker is strategically mounted on a withdrawable frame, ensuring convenient maintenance, efficient testing, and seamless replacement.

Perfect for scenarios demanding regular operation or routine maintenance.

While the installation is intricate and more expensive, it delivers superior adaptability.

Plug-in Type Installation:

The circuit breaker connects directly to the busbar via a plug-in connection, facilitating rapid installation and swift replacement.

Perfectly tailored for conditions necessitating rapid swaps.

-Secondary Wiring Method

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

Product testing

Mechanical operation test: This test is essential to confirm the seamless performance of the circuit breaker under various conditions.

Check whether the mechanical operation of the circuit breaker is smooth, flexible enough to adapt to changes, and consistently reliable, meeting the highest industry standards,without any compromise.

Test the operation functions such as the crucial actions of closing the circuit for connectivity,ensuring there is no delay, opening to ensure safe disconnection,and also energy storage, which ensures readiness for future operationsefficiently.

Electrical performance testing: These tests safeguard the electrical integrity and durability of our product.

Insulation resistance test: This involves the use of a megohmmeter to precisely measure the insulation resistance of both main and auxiliary circuits, ensuring they surpass the standard threshold (usually ≥ 1M Ω), guaranteeing safety and reliability.

Power frequency withstand voltage test: Administer rated power frequency voltage (such as 2500V/1min) to both the main and auxiliary circuits to rigorously assess insulation performance, ensuring no compromise.

Contact resistance test: Accurately measure the contact resistance of the main contact, ensuring it falls below the specified value (usually micro ohm level), thereby confirming optimal performance.

Protection function test: This test ensures the circuit breaker can efficiently protect against electrical anomalies.

Test the action values and response times of essential protection functions such as overload, which prevents overheating, short circuit which averts potential damage, and crucially, ground fault detection to prevent safety hazards,with precision.

Verify the comprehensive settings calibration and overallfunctionality assurance of the intelligent release device, confirming it operates seamlessly under all conditions.
