WTA150-01-D-N*P Series: High-Capacity Barrier Terminal Blocks for Heavy-Duty Power Control

TheWTA150-01-D-N*P is a professional-grade Barrier Terminal Block engineered by Telian (duanzitai) to deliver exceptional power distribution and high-safety electrical connections. Specifically designed for Electric Appliances and industrial power systems, this Screw Terminal Block provides a robust and organized termination point for high-voltage and high-current AC/DC applications.

Key Technical Highlights:

• Versatile Surface Finishing: To meet diverse environmental and conductivity requirements, this series offers multiple surface treatment options, including Nickel Plated, Silver Plated, and Tin Plated. These finishes provide superior corrosion resistance and ensure long-term, stable electrical contact.

• Robust 600V Power Handling: Engineered for heavy-duty performance, the WTA150 series supports a rated voltage of 600V. The housing is crafted from high-grade, flame-retardant Black PC material, offering superior insulation and mechanical strength in demanding industrial environments.

• Flexible Pitch & Configuration: To accommodate various safety clearance and creepage standards, this series is available in four distinct pitches: 9.5mm, 10.0mm, 11mm, and 14mm. With a scalable contact range from 2 to 30 positions, it offers the flexibility needed for customized PCB and power module layouts.

• Premium Material Integrity: The core conductive components feature high-purity Copper and Brass, ensuring minimal resistance and maximum transmission efficiency. The Tin-plated Brass pin headers are optimized for high-quality PCB integration, ensuring excellent solderability.

• Secure & Vibration-Resistant: The classic barrier design prevents accidental short-circuiting between adjacent terminals, while the heavy-duty screw mechanism provides a vibration-resistant connection—essential for industrial control and high-load frequency converters.

• Certified Manufacturing Excellence: Produced in Guangdong, China, under strict ISO and CE quality management protocols, ensuring every unit meets the rigorous safety standards required by global industrial partners.

TheWTA150-01-D-N*P series provides a dependable, high-density connection solution, ensuring your power systems remain stable, efficient, and secure under the most intensive operating conditions.
