-Factory Testing
Mechanical Operation Testing
Content: Execute a series of operations on the circuit breaker to ensure the opening and closing actions are both effortlessly smooth and reliably consistent.
Insulation Resistance Test
Content: Utilize an insulation resistance tester to meticulously evaluate the insulation resistance across each pole of the circuit breaker and between the pole and its casing.
Voltage Withstand Test
Content: Administer a high voltage (typically twice the rated voltage plus an additional 1000V) for 1 minute to inspect for any instances of breakdown or failure.
Temperature Rise Test
Content: Operate at rated current and accurately measure the temperature increase of the wiring terminals and contact points to ensure optimal performance.
-On-Site Testing
Power-On Test
Content: Verify that the circuit breaker can successfully open and close without issues after the power is activated.
Protection Function Test
Overload Protection: Simulate an overload condition and ensure the circuit breaker trips within the defined time frame.
Short Circuit Protection: Simulate a short circuit scenario and confirm the circuit breaker trips immediately as expected.
To ensure superior protection, we utilize shockproof materials to safeguard our products.
Material: High-quality foam and bubble film, among other materials.
Strategic Placement: Carefully position the protective materials evenly around the circuit breaker, both at the top and bottom, to maximize safety.
- External Packaging
External Shield: Our products are enveloped securely in robust cartons.
Material: Crafted from high-strength, corrugated cardboard boxes, ensuring durability throughout transit.
Carton Sealing
Method: Achieve a secure seal using top-grade tape or heavy-duty strapping.
Requirement: Maintain a securely sealed package to avert any possibility of box damage or cracking.
Identification and Labeling
Content:Meticulously detailed with product model, quantity, weight, manufacturer, and transportation labels (including fragile, upward, moisture-proof symbols, etc.)
Location: Prominently and clearly printed on the exterior of the cardboard box.
