Choosing the right terminal block requires matching voltage and current ratings to your system requirements, selecting an appropriate wire entry style, and considering the mounting method. Match the wire gauge capacity to your conductors and verify the block meets relevant safety standards for your application. What Do Terminal Blocks Do? Terminal blocks create secure, organized connections between wires without permanent splicing. They use mechanical clamping to hold conductors together inside an insulated housing. You’ll find them in industrial equipment where control wiring needs organized connection points. How Do Terminal Blocks Work? A terminal block clamps wire conductors against metal terminals using mechanical force. Insert a wire into the terminal opening and tighten the clamping mechanism. This creates a gas-tight connection that conducts electricity reliably while holding the conductor firmly in place. The insulated housing keeps adjacent connections separated. You can connect multiple wires to the same block without creating direct contact between circuits. This allows you to inspect or modify individual connections without affecting others. Terminal Block Types Terminal blocks vary based on mounting method, wire entry style, and clamping mechanism. Here are the main types: How do I choose the Right Terminal Block? Choosing a terminal block becomes easier when you evaluate things in order. Here’s what to consider: UK Terminal Block (Modular) Modular DIN Rail Mounting High-Insulation Housing (PA66) Secure Screw Clamp Connection IEC Certified for Reliability View Details & Specs Step 1: Calculate Current and Voltage Requirements Start by figuring out the maximum current your circuit will carry.

Wat is het verschil tussen een klemmenblok en een klemmenstrook?

12 november 2025

The main difference between a terminal block and a terminal strip is how they are structured. A terminal block is modular and insulated, allowing you to add or remove sections on a DIN rail. A terminal strip, meanwhile, is one fixed row of screw terminals used for simple wire-to-wire connection. What Is a Terminal Block? The best way to define terminal block is to see it as a modular connector that secures two or more wires inside an insulated housing. Inside the block, a metal conductor transfers current while a clamping mechanism (screw, spring, or push-in) holds the wire firmly in place. It gives you a safe wiring point without permanent splicing. What Is a Terminal strip? A terminal strip is a single fixed row of screw terminals used to connect wires point-to-point. Each section has a metal conductor with a screw on top, allowing the wire to be fastened securely. Unlike a modular terminal block, a terminal strip comes as one long piece and does not mount on a DIN rail. It is mainly used for simple wiring connections where circuits do not need frequent changes. How Are Terminal Blocks and Terminal Strips Different? The simplest way to compare terminal strip vs terminal block is by looking at structure, flexibility, and safety. The table below shows how each functions in an electrical setup. Terminal Block vs Terminal Strip (Quick Comparison) Category Terminal Block Terminal Strip Structure Modular connector with individual insulated terminals Single fixed strip with multiple screw terminals in one piece Wiring Flexibility […]
