- In-Factory Testing Procedures
Mechanical Operation Testing
Content: Repeatedly operate the circuit breaker to ensure the opening and closing mechanisms are both flexible and highly reliable.
Insulation Resistance Test
Content: Utilize an insulation resistance tester to accurately measure the insulation resistance between each pole of the circuit breaker and the casing, ensuring superior safety.
Voltage Withstand Test
Content: Apply a high voltage, typically twice the rated voltage plus 1000V, for 1 minute. Observe for any breakdown to guarantee enduring strength.
Temperature Rise Test
Content: Operate at rated current and diligently measure the temperature rise at wiring terminals and contacts to confirm optimal performance.
- On-Site Testing
Power-On Test
Content: Verify the circuit breaker can open and close efficiently after power is applied, ensuring it functions reliably.
Protection Function Test
Overload Protection: Simulate an overload condition and verify the circuit breaker trips within the specified time, ensuring maximum safety.
Short Circuit Protection: Simulate a short circuit condition and confirm the circuit breaker trips instantly, ensuring absolute protection.
Our circuit breakers are enveloped in shockproof materials
Material: Foam and bubble film, among others
Placement: Strategically placed evenly around the circuit breaker, including the top and bottom, to ensure maximum protection
-External packaging
We use durable cartons
Material: Crafted from high-strength corrugated cardboard
Carton sealing
Method: We ensure our cartons are securely sealed with high-quality tape or robust strapping
Requirement: This ensures a secure seal to prevent any cracking during transit
Identification and labeling
Content:Each package is clearly marked with the product model, quantity, weight, manufacturer, and essential transportation labels (such as fragile, upwards, moisture-proof, etc.)
Location: These details are prominently printed on the exterior of the cardboard box.
