-Factory testing
Mechanical operation testing
Content: Conduct repeated operations of the circuit breaker to ensure the smooth and dependable functioning of opening and closing mechanisms.
Insulation resistance test
Content: Utilize an insulation resistance tester to accurately assess the insulation resistance between each pole of the circuit breaker and the outer casing, ensuring optimal safety measures.
Voltage withstand test
Content: Subject the circuit breaker to a high voltage (typically twice its rated voltage plus 1000V) for 1 minute to verify the absence of any breakdown.
Temperature rise test
Content: Operate at rated current and meticulously record the temperature rise at the wiring terminals and contact points to ensure they remain within safe limits.
-On site testing
Power-on test
Content: Confirm the circuit breaker's ability to open and close reliably when powered on.
Protection function test
Overload protection: Simulate an overload condition to ascertain that the circuit breaker trips within the specified timeframe.
Short circuit protection: Create a short circuit scenario to ensure the circuit breaker responds instantly by tripping.
For optimal protection, our inner packaging utilizes shockproof material
Material: including high-quality foam and robust bubble film, etc
Placement: These materials are strategically placed around the circuit breaker, ensuring complete coverage at both the top and bottom
-External packaging
The external layer features a durable carton
Material: High strength corrugated cardboard box
Carton sealing
Method: We ensure reliability by sealing with reinforced tape or industrial-grade strapping
Requirement: This ensures the integrity of the seal, preventing any potential cracking or damage to the box
Identification and labeling
Content:Essential details like product model, quantity, weight, and manufacturer's information, along with transportation labels (such as fragile, upward, moisture-proof, etc.)
Location: Prominently displayed on the exterior of the cardboard box for easy identification.
Transport
Domestic transportation
For domestic deliveries within China, direct coordination with designated freight forwarders ensures efficient transfer to the specified destination, utilizing either road transportation or domestic express services upon completion of production
International transport
In scenarios where a swift delivery of smaller quantities is required internationally, we collaborate with leading express courier services to reach the specified overseas location, leveraging the reliability of renowned names like
DHL, FEDEX, and UPS
Sea freight/air freight
For larger shipments and when time constraints are less pressing, we opt for sea freight. We liaise with a trusted freight company, arranging for secure transport via trucks to the designated port for warehousing. Subsequently, the goods are shipped by sea to the customer's specified port, where they can be collected with the necessary bill of lading.
