<p>The invention relates to a connection and base part for accommodating a pluggable surge arrester, comprising a base (13) and a U-shaped part (17), which is connected or can be connected to the base (13) and has guide and/or latching means for accommodating the complementarily designed surge arrester on the mutually facing limb inner sides, a telecommunication switch (11), which is inserted in the base (13), with connections (21) passed to the outside and an actuating device, which is connected to the telecommunication switch (11) and has a plunger (8), which is accessible via a cutout in the limb connecting section of the U-shaped part (17) in order to be operatively connected to a function display, a thermal release or another monitoring device of the pluggable surge arrester. According to the invention, a connecting link-type, groove-shaped guide (12) is introduced in the base (13) and has a continuously arcuate or arcuate/linear profile, wherein the guide (12) extends between the plunger (8) and the telecommunication switch (11). Furthermore, an actuating rail (9), whose form is similar to that of the connecting link, is inserted into the guide, wherein this actuating rail, with an integral design, has the plunger (8) and an areal part (10) for activating the telecommunication switch (11).</p> |
