As a trusted Terminal Blocks Supplier, RHT provides a wide range of high-performance terminal connectors for various industries. Our expertise in terminal blocks, including PCB terminal blocks, ensures reliable and durable electrical connections for industrial, commercial, and domestic applications.

What Are Terminal Blocks?

Terminal blocks are insulated electrical connectors that secure and connect two or more wires. These essential components facilitate the safe connection of circuits, ensuring efficient wiring and preventing accidental disconnections. Terminal blocks, also known as connection blocks or terminal strips, are widely used in industrial automation, power distribution, and control systems.

Applications of Terminal Blocks

Terminal blocks are critical for industrial power, automation, control, and signal applications where multiple connections are necessary. These connectors are typically mounted on DIN rails or fixed into electrical panels and enclosures. As a reliable Terminal Blocks Supplier, we ensure that our products meet the highest safety and quality standards.

Termination Types for Terminal Blocks

Terminal blocks are categorized by their termination types, each suitable for different environments and applications. Understanding the connection technology is essential for selecting the right terminal block for your needs.

1. Screw Clamp Terminal Blocks

Screw clamp terminals are the most common connection type. Conductors are inserted and pressed against a conductor strip by tightening a screw. This ensures a secure and durable connection.

2. Spring Clamp Terminal Blocks

Spring clamp terminals use a spring-operated mechanism. A screwdriver opens the clamp, allowing the wire to be inserted. Once released, the clamp securely holds the wire. These terminals are ideal for environments prone to vibration.

3. Push-in Connection Terminal Blocks

Push-in terminal blocks allow conductors to be inserted directly into the connection gap. This tool-free installation method is efficient and reduces installation time. Our Terminal Blocks Supplier catalog includes various push-in options.

Design Considerations for Terminal Blocks

• Safety Ratings – Our terminal blocks comply with UL and IEC safety standards.

• Current and Voltage Ratings – We recommend selecting terminal blocks rated for 150% of the system's maximum current.

• Handling and Safety – Terminal blocks provide safe, durable, and organized connections within industrial panels.

• Customization – Different housing colors and markings can enhance identification and simplify complex wiring systems.

Wire-Entry and Securing Methods

• Wire-Entry Orientations – Horizontal (90°), vertical (180°), and 45°

• Wire-Securing Methods – Screw terminals, push buttons, and push-in options
