1 Overview
Danfoss Connecto NA is a family of connection kits for self-regulating heating cables (trace heaters).
The Connecto NA connection kits are simple and safe to use, yet faster to install and more cost effective
than conventional systems. They can be used with Danfoss PX/RX heating cables in fixed equipment
heating systems for multiple applications (e.g. heating of pipes, roof and gutter de-icing etc.).
