-Factory Testing
Mechanical Operation Testing
Content: Operate the circuit breaker multiple times to ensure that the opening and closing functions are both flexible and reliable.
Insulation Resistance Test
Content: Utilize an insulation resistance tester to accurately measure the insulation resistance between each pole of the circuit breaker and between the pole and its casing.
Voltage Withstand Test
Content: Apply a high voltage, typically double the rated voltage plus an additional 1000V, for a duration of 1 minute to ensure there is no breakdown.
Temperature Rise Test
Content: Operate at rated current and monitor the temperature rise at wiring terminals and contacts to ensure safety and endurance.
-On Site Testing
Power-On Test
Content: Verify that the circuit breaker can open and close smoothly and effectively post power activation.
Protection Function Test
Overload Protection: Simulate an overload condition and check that the circuit breaker trips within the designated time frame.
Short Circuit Protection: Simulate a short circuit and ensure the circuit breaker trips instantly to provide optimal protection.
To ensure the utmost protection, we use shockproof materials to safeguard the product.
Material: Our choice of materials includes high-quality foam and reliable bubble film, etc.
Placement: Strategically positioned around the circuit breaker, both at the top and bottom, for maximum protection.
-External packaging
We utilize robust cartons designed to endure transit challenges.
Material: Crafted from high-strength corrugated cardboard box, providing enhanced durability.
Carton sealing
Method: Our sealing technique involves using high-quality tape or secure strapping
Requirement: Ensure a perfect seal to prevent any risk of box damage or cracking during transit.
Identification and labeling
Content:Essential information such as product model, quantity, weight, and manufacturer details are included, along with important transportation indicators (including fragile, upward orientation, moisture-proof warnings, etc.)
Location: All labels are prominently displayed on the exterior of the cardboard box for easy identification.
Transport
Domestic transportation
For local deliveries within China, if you have appointed a specific freight forwarder, our team will ensure prompt delivery to the designated location using reliable road transportation or trusted domestic express services promptly upon production completion.
International transport
In cases where the shipment size is small and time constraints are critical, and a specific international destination is required, we partner with leading international express carriers like
DHL, FEDEX, and UPS
Sea freight/air freight
For larger shipments without urgent deadlines, sea freight is our preferred method. We collaborate with reputable freight companies, coordinating trucking services to collect and transport goods to the designated port for secure warehousing. Finally, the shipment is transported by sea to the customer's specified port, where pickup is facilitated with a bill of lading.
