Product's Details

Distribution box

*Rated working voltage up to AC 380V, suitable for power distribution in both industrial and civil scenarios.

*Protection class IP54, effectively dustproof and waterproof, adaptable to humid and dusty complex environments.

*Made of 1.2mm thickened cold-rolled steel plate, the cabinet's compressive strength is increased by 30% for long-term durability.

*Built-in 6-12 circuit terminals, supporting simultaneous access of multiple circuits to meet diversified power consumption needs.

*Short-circuit breaking capacity up to 10kA, quickly cutting off fault current to ensure the safety of the circuit system

Distribution box

*Overall weight only 18kg, compact size (600×400×200mm), easy to install and carry.

*Temperature rise controlled within ≤40℃, maintaining stable performance even under long-term full-load operation.

*Equipped with high-precision ammeter and voltmeter with error ≤±1%, monitoring circuit parameters accurately in real time.

*The cabinet's heat dissipation holes adopt louvered design, with heat dissipation efficiency increased by 35%, avoiding aging of internal components due to high temperature

*Mean Time Between Failures (MTBF) exceeds 50000 hours, reducing operation and maintenance costs by 40%

Distribution box

*The wiring terminals are made of pure copper, with conductivity increased by 25%, reducing power transmission loss.

*The cabinet door is equipped with a three-point anti-theft lock, with anti-theft coefficient increased by 50%, reducing the risk of equipment theft.

*With overload protection function, the protection will automatically start when the overload current exceeds 15% of the rated value.

*The surface adopts electrostatic spraying process, with a coating thickness of 80μm, significantly enhancing anti-corrosion and anti-rust capabilities.

FAQ

FAQ

Q: What is the production lead time for your distribution boxes?
A: The production lead time for standard model distribution boxes is 7-10 working days. For customized products, the lead time is 15-25 working days depending on the complexity of requirements, and the delivery time for bulk orders can be shortened through negotiation.

Q: Does the factory support OEM/ODM customization services for distribution boxes?
A: Yes, we do. We can customize cabinet size, color, internal component configuration and brand logo according to the drawings, parameters and functional requirements provided by customers. The minimum order quantity for customized orders is 50 units.

Q: What testing procedures do distribution boxes undergo before leaving the factory?
A: Each distribution box must go through four core testing procedures: 100% power-on test, withstand voltage test, short-circuit protection test and protection level test, with a test pass rate of 99.9% to ensure product quality.

Q: Can the factory provide supporting installation guidance and follow-up maintenance suggestions for distribution boxes?
A: Yes, we will provide customers with detailed paper and electronic installation manuals, and also have a professional technical team that can provide free 1-year technical maintenance consulting services via online video or phone.
