CD-K System — 25 ... 40 A © Siemens AG 2007 Introduction Accessories for IP55 Trunking units The higher degree of protection IP55 is achieved by fitting an additional seal and a flange at the tap-off point and by sticking pads over the connection fixtures. Tap-off plugs The degree of protection IP55 is achieved by fitting additional seals at the tap-off point.
