- Factory Testing
Mechanical Operation Testing
Content: Operate the circuit breaker multiple times to meticulously ensure that the opening and closing are both flexible and reliably consistent.
Insulation Resistance Test
Content: Utilize an insulation resistance tester to precisely measure the insulation resistance between each pole of the circuit breaker and between the pole and the casing to ensure optimal safety standards.
Voltage Withstand Test
Content: Apply a high voltage (typically twice the rated voltage plus an additional 1000V) for 1 minute and diligently check for any signs of breakdown to guarantee durability.
Temperature Rise Test
Content: Operate at rated current and accurately measure the temperature rise of wiring terminals and contacts to maintain efficiency.
- On-site Testing
Power-on Test
Content: Verify that the circuit breaker can open and close smoothly and efficiently after being powered on.
Protection Function Test
Overload Protection: Simulate an overload condition and confirm if the circuit breaker trips within the specified timeframe to ensure protection.
Short Circuit Protection: Simulate a short circuit and assess if the circuit breaker trips instantly, safeguarding the entire electrical system.
Shield your circuit breaker with confidence using our superior shockproof materials.
Material: Premium foam and bubble film, among other protective materials.
Placement: Strategically place around the circuit breaker, ensuring top and bottom coverage for optimal protection.
-External packaging
Fortified carton
Material: Crafted from high-strength corrugated cardboard box for unwavering durability.
Carton sealing
Method: Impeccably seal with industrial-grade tape or reinforced strapping
Requirement: Achieve a robust and secure seal to avert any potential cracking of the box during transit.
Identification and labeling
Content:Display product model, quantity, weight, manufacturer details, and essential transportation labels (including fragile, upward, moisture-proof instructions, etc.)
Location: Ensure clarity with information prominently printed on the exterior of the cardboard box.
Transport
Domestic transportation
For domestic routes in China, products are transported smoothly to designated locations via efficient road transportation or reliable domestic express delivery immediately post-production.
International transport
For small shipments with time-sensitive delivery to assigned international locations, we collaborate with leading global express carriers
DHL, FEDEX, and UPS.
Sea freight/air freight
For larger shipments where time allows, we prefer sea freight, utilizing a reputable freight companyto arrange for trucks to collect goods and transition them to the designated port for secure warehousing. Finally, goods are smoothly transported by sea to the customer's chosen port, where collection is facilitated with a bill of lading.
