Does anyone recall what these are for? I know that they need to be removed in some applications but I can't remember why. Thanks, Mike

You should be able to find a manual for the 6RA24 under the Simoreg K section of the support pages. http://support.automation.siemens.com/WW/llisapi.dll/csfetch/15274922/6RA24_englisch.pdf?func=cslib.csFetch&nodeid=21382254
