In modern electrical installations, DIN-rail terminal blocks are essential connection components. With the increasing demand for automation and time-saving, choosing the right type of terminal block has become even more important. Spring-cage and screw type DIN-rail terminal blocks, as two common types, differ in the time required for installation, directly affecting the overall efficiency of the project. This article will compare these two types of terminal blocks to help you make a more informed choice for your project.
Advantages of Spring-cage type DIN-rail terminal blocks
Spring-cage type DIN-rail terminal blocks use an insert design with a built-in spring mechanism that automatically clamps the cable. The installation process is very simple. After inserting the cable into the terminal, the spring immediately tightens the cable, without the need for any additional tools or manual tightening. For electrical systems that require fast installation in large quantities, spring-cage terminal blocks significantly reduce the time spent on manual operation.
Compared to traditional screw type terminals, spring-cage terminals reduce the reliance on tools, provide faster installation, and lower the risk of poor contact caused by improper installation. This makes Spring-cage type DIN-rail terminal blocks the preferred choice for large-scale automation projects.
Characteristics of screw type DIN-Rail Terminal Blocks
Screw type DIN-rail terminal blocks are the most common traditional type, where the cable is secured by tightening screws. While screw type terminals offer a certain advantage in electrical contact reliability, their installation process is more complicated. Installers need to use tools to tighten each screw individually and check the tightness to ensure a secure connection. This process is time-consuming, labor-intensive, and requires more manual intervention.
Especially when large amounts of wiring are involved, screw type terminals are far less efficient in installation compared to spring-cage terminals. Therefore, while screw type terminals still have stability advantages in certain specific applications, their installation time is clearly a major disadvantage.
Installation Time Comparison
To illustrate the differences in the installation process of the two types of DIN-rail terminal blocks, here is a comparison of their installation times:
| Feature | Spring-Cage Type DIN-Rail Terminal Block | Screw Type DIN-Rail Terminal Block |
| Installation Method Insertion type | automatic cable clamping, no tools required | Screw tightening, requires tools |
| Installation Time | About 10 seconds per terminal | About 30 seconds per terminal |
| Ease of Operation | Simple and intuitive, no tools needed | Requires tools, more complex operation |
| Suitable Scenarios | Large-scale installations, fast wiring | Small-scale or precise installations, for specific requirements |
From the comparison table above, it is evident that Spring-cage type DIN-rail terminal blocks are significantly faster to install than screw type terminals. For large-scale installations, spring-cage terminals can effectively save a significant amount of labor and time costs.
When selecting DIN-rail terminal blocks, considering the difference in installation times, Spring-cage type DIN-rail terminal blocks are undoubtedly the more efficient choice. By simplifying the installation process and reducing the need for tools, they significantly improve installation efficiency, making them particularly suitable for applications that require large-scale and fast wiring.
If your project focuses on saving installation time and overall efficiency, Spring-cage type DIN-rail terminal blocks are certainly the better option. In contrast, while screw type terminals have advantages in stability, their complicated and time-consuming installation process makes them less suitable for large-scale applications.
