-Factory testing
Mechanical operation testing
Content: Engage the circuit breaker repeatedly to ensure seamless operation, assessing whether the opening and closing mechanisms remain effortlessly flexible and impeccably reliable.
Insulation resistance test
Content. Employ an insulation resistance tester to precisely measure the insulation resistance between each pole of the circuit breaker and the outer casing, ensuring robust safety and performance.
Voltage withstand test
Content: Administer a high voltage (typically twice the rated voltage plus an additional 1000V) for 1 minute to verify the absence of breakdown, ensuring the integrity of the circuit under demanding conditions.
Temperature rise test
Content. Facilitate operation at rated current and meticulously measure the temperature rise at the wiring terminals and contacts, ensuring optimal thermal management.
-On site testing
Power-on test
Content: Confirm that the circuit breaker can open and close smoothly and reliably under power-on conditions.
Protection function test
Overload protection: Simulate overload conditions and verify that the circuit breaker initiates a trip within the designated timeframe to prevent damage.
Short circuit protection: Simulate a short circuit scenario and ensure the circuit breaker reacts by tripping instantly, safeguarding the system from potential hazards.
Shockproof material
Materials used: Premium foam, protective bubble film, among others
Placement: Strategically position around the circuit breaker, ensuring coverage on both top and bottom
-External packaging
Sturdy carton
Material: High-strength corrugated cardboard box for optimal protection
Carton sealing
Method: Securely seal with durable tape or robust strapping
Requirement: Guarantee an airtight seal to prevent any potential cracking of the box
Identification and labeling
Content includes:Detailed product model, precise quantity, weight, manufacturer info, and necessary transportation labels (such as fragile, handle with care, moisture-proof, etc.)
Location: Prominently and clearly printed on the exterior of the cardboard box.
