Import Barrier Terminal Block Pitch:8.25mm — Buy in wholesale FOB from Supplier in China

Shenzhen Starpai Technology Co., Ltd. manufactures barrier terminal blocks with 8.25 mm pitch, configured from 2 to 24 poles, with a rated voltage of 300 V and current capacity of 20 A. The conductor uses tin-plated brass, the insulating case is PA66 with 15 percent glass fibre reinforcement, and the terminal screw is M3 C1018 steel with nickel plating. Electrical withstanding voltage is tested at AC 2500 V for one minute, with isolation resistance of 1000 megaohms minimum at DC 500 V. The wire range accommodates 22-12 AWG with a strip length of 8-10 mm and maximum torque of 4 kgf.cm. Operating temperature spans -33 degrees C to +105 degrees C.

The PA66+15%GF case material provides improved dimensional stability and creep resistance compared to unreinforced nylon, which is significant for maintaining pitch accuracy during screw tightening and thermal cycling. Tin-plated brass offers acceptable conductivity and solderability while resisting oxidation in moderate environments; for marine or high-humidity applications, buyers may need to confirm whether a thicker tin or alternative plating such as nickel or silver is available. The C1018 steel M3 screw with nickel plating is standard for this product class, though thread-forming or thread-cutting variants may be offered for different panel materials. The 8.25 mm pitch is a recognised spacing in power terminal block design, balancing current-carrying capacity with board space.

Typical applications include power distribution in industrial control panels, automotive wiring harnesses, and HVAC equipment where through-panel or PCB-mounted barrier termination is required. The 2-24 pole range allows modular assembly for varying circuit counts. Buyers should confirm with Shenzhen Starpai whether RoHS and REACH compliance certificates are available, and whether the 300 V rating meets specific market requirements such as UL 1059 or IEC 60947-7-1. Custom pole counts beyond 24, alternative plating, and packaging for automated assembly should also be discussed directly with the supplier.

Shenzhen Starpai Technology Co., Ltd. is located at 14# Building, Lixin Road, Buji, Nanwan Sub-District, Shenzhen 518114, Guangdong Province, China. This places the company within Shenzhen's mature electronics manufacturing ecosystem, with access to component supply chains and logistics infrastructure. The supplier holds a harbor trust tier, indicating basic verification. Response rate is recorded at 0.00 percent with zero average response hours, suggesting that platform messaging may not be reliable and direct contact through alternative channels may be necessary.

The listing does not state year of establishment, factory floor space, employee count, annual revenue, ISO certification status, or named clients. There is no indication of whether production is in-house or subcontracted, or whether the company operates as an OEM, ODM, or trading entity. Buyers should request a factory profile, quality management system certificates, and reference customers before committing to volume orders. The address in Buji, Longgang District, is within an established industrial zone, but this does not alone confirm manufacturing capability.
