Import Din Rail Terminal Block Ukk Series — Buy in wholesale FOB from Supplier in China

The CROP Technology Group UKK Series din rail terminal blocks are designed for power distribution in high-voltage cabinets and distribution panels, with current ratings from 85A to 520A and voltage ratings up to 690V AC per IEC standards. Each model features distinct conductor configurations: the CRUKK-80 supports one input of 6 to 16mm² and four outputs of 2.5 to 6mm² plus two of 2.5 to 16mm², while the CRUKK-500 handles a single input of 3x15.5x0.8 to 8x24mm² alongside multiple output ranges. Dimensions vary by model, with the CRUKK-80 measuring 30x69x49mm and the CRUKK-500 at 49x96x50mm, ensuring compatibility with standard 35mm DIN rails.

Terminal contacts are made from tinned brass for enhanced conductivity and corrosion resistance, while the housing is constructed from flame-retardant nylon, meeting UL94 V-0 standards for fire safety. Screws are metric-threaded zinc steel, suitable for repeated terminations without stripping. The transparent cover allows visual verification of connections, and captive screws are pre-retracted to reduce installation time. These blocks support parallel connection via jumper wires when multiple inputs are required, and mounting options include clip-on DIN rail or panel screws with a 95% fill ratio for secure conductor retention.

These terminal blocks are commonly purchased by industrial automation integrators, electrical panel builders, and OEMs in machinery and energy distribution sectors. They are typically shipped in bulk packaging of 50 to 100 units per carton, with lead times of 2 to 4 weeks depending on order volume. Trade terms are typically FOB Ningbo or Shanghai, with payment via T/T or L/C. Buyers should confirm compatibility with their DIN rail profile and verify the exact conductor range for each terminal position before ordering.

CROP Technology Group operates from Yueqing, Zhejiang, China, a region known for electrical component manufacturing. The company is listed as an imported supplier with harbor trust tier, indicating verified export documentation and logistics capability. There is no public information on company size, revenue, or years in business. The listing confirms production and export of terminal blocks but does not state certifications, client names, or quality management system compliance.

The supplier does not provide response rate or average response time, suggesting limited direct buyer engagement. Product documentation is available via catalog download, indicating technical support readiness. Buyers should request sample units and verify material test reports independently, as no ISO, CE, or RoHS claims are made in the listing. The facility is assumed to be a production unit based on product specificity and location, but no factory audit reports are disclosed.
