Pre-insulated ferrule – PKE412
PKE412 is a pre-insulated ferrule from Cembre, designed for flexible copper conductors with stranded wire construction. The product comes with a polyamide (PA6) insulation sleeve in orange and an electrolytic tin-plated copper tube construction. PKE412 is specified for 4 mm² conductors, and the length (L) in the product table is 12 mm.
What PKE412 does and how it is used
PKE412 ensures a mechanically stable termination of stripped, multi-stranded copper conductors at the transition between conductor and contact point. The sleeve visually indicates the size; the electrical connection is established via the tin-plated copper tube. For correct installation, it is recommended to follow the manufacturer's instructions for stripping, insertion, and crimping.
Installation
- Strip the conductor to the specified length L (12 mm for PKE412).
- Avoid damaging the conductor's strands; ensure a neat, evenly cut insulation.
- Insert the conductor fully into the ferrule, so that the conductor does not protrude from the end of the ferrule.
- Use recommended crimping tools such as ZKE610N or ZKE616N. Depending on the length of the ferrule, it may be necessary to perform two overlapping crimps.
Documentation and installation instructions from the manufacturer describe both materials and assembly procedure. See datasheet from the manufacturer
