The role of terminal blocks have the following:
(1) beautiful. Terminal block to the box part and the door is separated from the control line, and looked so beautiful and neat, so that the control lines unlike the spider web is then chaos.
(2) ease of installation. Installed on the terminal block and terminal, as long as the corresponding line number received in place of the simply do not want to control the loop is what really quickly, very convenient.
(3) to facilitate maintenance. The process of using the issue, whether the boundaries of the terminal voltage can directly multimeter measuring terminal blocks corresponding to quickly identify the fault (of course, the control circuit 220V better than 380V control circuit investigation), check line is also easy to check, because the terminal the rafts will have a terminal number, the corresponding figures are generally received the corresponding contacts in the control loop.
(4) facilitate the installation of remote control. Remote control directly from the terminal block wiring, so there is no need to make changes to the original control loop.
