Siemens 3RS2

To make optimum use of available terminal space, you are advised to choose a form of crimping
that creates a corresponding rectangular contour. Trapezoidal crimping is highly suitable in this
case.
When a conductor is used that utilizes the full overall height, the terminal spring is de󹪞ected to
the maximum. It may therefore be di󹪟cult to remove this conductor because it requires further
de󹪞ection of the spring.

conductors equipped with end sleeves.
For wiring 󹪝nely-stranded or stranded conductors without end sleeves on spring-type (push-in)
terminals, a screwdriver is required to open the spring terminal.
Tool
DIN 5264 screwdriver with size 0.5 x 3 mm (for 󹪝nely-stranded conductors only). (Article
