The screw connection: terminal block connection technology is the most famous is also the most popular worldwide. This connection technology designed series selos, the series can achieve 0.14 ~ to 240mm2's wiring. The large contact area, the resistance is small, the size of the contact force has nothing to do with the cross-sectional area.
 
The elastic connection: can use fasis series. This terminal block is divided into WKFN series and BIT-S series, the former relay spring technology, applicable to industrial fields; the latter using the card spring technology for installation in the building. Shock contact the application of the technology connection in the range between 0.14 ~ 35mm2.

Taris series, the technology can be direct connect, do not have to wire prior to, do not knock down the wire end sleeve. This is when a processing is considered cost-effective connection technology. This terminal is designed for connectivity range of less than 2.5mm2. This technology to save time up to 60% compared to traditional wiring techniques.

Terminal blocks play an important role in the electrical connection. Precisely because the terminal block these advantages to become the first choice of number of connections, I believe, terminal will play a more important role in the process of constant development of future electrical power.
