Installation Instructions
-Ensure secure and precise placement by installing within the panel.
Installation method:
Choose a fixed installation for enhanced stability and reliability.
Distribution box: Positioned inside the distribution box to guarantee steadfastness and security.
Vertical installation
Direction: For optimal performance, install vertically with the operating handle elegantly facing upwards.
Avoid: Refrain from inverted installation unless explicitly allowed by the product specifications.
Connection
Power cord: Neatly connect to the input terminals of the circuit breaker, labeled as 'L1', 'L2', 'L3'.
Load line: Securely attach to the output terminals, designated as 'T1', 'T2', 'T3'.
Grounding wire: If a grounding terminal is available, ensure it is firmly and effectively connected.
Distance requirements
Spacing: Maintain adequate distance from other devices to facilitate efficient heat dissipation and convenient maintenance.
Reference: Consult the product manual for detailed spacing guidelines.
Safety precautions
Power off operation: Always cut off power during installation to safeguard against electric shock.
Protective equipment: Utilize insulated gloves and protective goggles for safety.
Standard compliance: Diligently adhere to the electrical installation standards for safe and compliant operations.
Product testing
- Factory testing
Mechanical operation testing
Content: Operate the circuit breaker multiple times to ensure seamless functionality, verifying whether the opening and closing are both flexible and impeccably reliable.
Insulation resistance test
Content. Deploy an insulation resistance tester to meticulously measure the insulation resistance among each pole of the circuit breaker and between the pole and the casing, ensuring optimal safety and performance.
Voltage withstand test
Content: Subject the system to a high voltage (typically twice the rated voltage plus 1000V) for 1 full minute and vigilantly inspect for any breakdowns, ensuring robust durability.
Temperature rise test
Content. Use the rated current to thoroughly measure the temperature rise of wiring terminals and contacts, certifying it remains within safe operational limits.
- On-site testing
Power-on test
Content: Confirm the circuit breaker can open and close seamlessly and reliably once powered on.
Protection function test
Overload protection: Simulate an overload condition and ensure that the circuit breaker trips within the precise specified time, maintaining system integrity.
Short circuit protection: Simulate a short circuit event and verify that the circuit breaker trips instantaneously, providing immediate protection.
Packaging & Shipping
-Inner Packaging
Our inner packaging is designed for maximum protection, utilizing advanced shockproof materials.
Material: High-quality foam and bubble film, among other protective materials,
Placement: Meticulously placed around the circuit breaker, ensuring coverage at both the top and bottom for optimal security.
-External Packaging
