- By adopting the newly developed "wiring disconnection prevention structure" that regulates the normal positional relationship between the crimp terminal and terminal screw, we prevent wiring disconnection accidents that may occur during on-site construction. - By adopting the "finger protection structure" that prevents direct contact with the terminal area, we prevent electric shock accidents in advance. - Both the upper and lower sections of the terminal unit come standard with terminal covers. Additionally, for the lower section, there are two installation positions for the marking band, on the inside and outside, allowing for installation at your preferred location. - The use of a test jig that allows for one-touch connection dramatically reduces the setup man-hours for testing and inspection. - By adopting the color "gray" for the unit, it can be easily distinguished from conventional terminal blocks.
