- In-Factory Testing
Mechanical Operation Testing
Content: Engage the circuit breaker in repeated operations to assess whether the opening and closing are both smooth and dependably consistent.
Insulation Resistance Test
Content: Utilize an insulation resistance tester to meticulously measure the insulation resistance between each circuit breaker pole and between the pole and its casing.
Voltage Withstand Test
Content: Administer a high voltage (generally double the rated voltage plus an additional 1000V) for 1 minute and inspect for any signs of breakdown or failure.
Temperature Rise Test
Content: Operate continuously at rated current and accurately measure the temperature increase at the wiring terminals and contact points.
- On-Site Testing
Power-On Test
Content: Verify that the circuit breaker can open and close normally once powered on, ensuring seamless operation.
Protection Function Test
Overload Protection: Simulate an overload and confirm that the circuit breaker trips within the predetermined timeframe.
Short Circuit Protection: Simulate a short circuit and ensure the circuit breaker trips instantaneously as a safeguard.
Utilizing shockproof materials
Material: premium foam, bubble film, and more
Placement: Strategically placed around the circuit breaker for optimal protection, ensuring coverage at both the top and bottom
-External Packaging
sturdy carton
Material: High-strength corrugated cardboard box
Carton Sealing
Method: Meticulously sealed with durable tape or reliable strapping
Requirement: Guarantee a robust seal to effectively prevent any cracking of the box
Identification and Labeling
Content:Precise product model, quantity, weight, manufacturer details, and essential transportation labels (such as fragile, upward, moisture-proof, etc.)
Location: Clearly printed on the exterior of the cardboard box for easy visibility.
