NaiHang Brass Terminal Blocks offer high conductivity, precision CNC machining, corrosion resistance, and customizable configurations for industrial use.

Product Overview

Introduction: Brass Terminal Block for Power Distribution

NaiHang’s brass terminal blocks offer a reliable solution for power distribution, grounding, and neutral connections in industrial and electrical applications. Designed to serve as a robust brass wiring block, these terminal blocks ensure stable electrical connectivity in control panels, distribution boxes, and grounding bars.

Material Excellence: High-Grade Brass for Superior Performance

Manufactured using high-quality brass alloys (H59 and H62), NaiHang terminal blocks provide exceptional electrical conductivity and mechanical strength compared to standard zinc alloy alternatives. This material choice guarantees long-lasting performance, making these brass neutral links suitable for heavy-duty terminal block applications where durability and safety are critical.

Surface Treatment: Corrosion Resistance and Durability

To enhance corrosion resistance and extend service life, NaiHang offers nickel-plated or tin-plated finishes on the brass connector surfaces. These surface treatments protect the electrical connector strip from oxidation and wear, ensuring reliable screw terminal block performance even in harsh environments.

By combining premium materials with advanced plating options, NaiHang brass terminal blocks deliver a dependable grounding bar and distribution terminal block solution designed for global industrial standards.

Key Features & Benefits of Brass Terminal Blocks

Our brass terminal blocks are built to deliver reliability and ease in every connection. Here’s what sets them apart:

• Precision Machining CNC-machined brass bars provide accurate threads for tight, secure wire clamping—no slips or loose contacts.
• Robust Insulation The insulating base, made from PA66 or PC material, meets UL94 V-0 flame retardancy and handles heat well to keep connections safe.
• Secure Connection Screw terminals come in Slot or Phillips head types, designed to resist high torque and avoid thread stripping even under frequent tightening.
• Versatile Mounting Options These blocks fit standard 35mm DIN Rails perfectly and also support direct panel mounting, making installation flexible and straightforward.

With these features, our brass terminal blocks ensure solid electrical connections for various applications including grounding bars and distribution terminal blocks. For tailored grounding or neutral links, explore our NHA15 neutral bar link for a reliable DIN rail-mounted solution.

Installation & Safety Guidelines

Proper installation of brass terminal blocks is crucial for reliable performance and safety. Follow these key points to ensure secure connections and prevent issues like heat buildup:

• Wire Stripping Length: Strip the wire insulation to the recommended length—usually around 10-12mm—to allow the wire to fit snugly into the brass wiring block without exposing excess conductor.
• Torque Settings: Use the correct torque on screw terminals to ensure a firm connection without damaging the threads or wire. Over-tightening can strip screws or deform the wire, while under-tightening may cause poor contact and overheating.
• DIN Rail Mounting: When mounting on a 35mm DIN rail, snap the terminal block firmly into place. Avoid forcing it, as improper snapping can damage the insulating base or cause loose mounting.
• Screw Tightening: Use a suitable screwdriver (slot or Phillips head depending on the terminal block type) and tighten screws evenly. Check regularly for loosening during maintenance to maintain a secure connection.

By following these guidelines, you reduce the risk of electrical faults, improve current flow, and extend the lifespan of your brass neutral link or grounding bar assemblies. For detailed instructions on DIN rail setups, you can check our DIN rail terminal blocks product page.
