Junction box
The metal junction box has a PG21 conduit hub on each end. The
box is anchored to the body of the transformer with screws and
can be easily attached, simplifying installation and change-out
procedures. The junction box has IP 54 according to standard
EN 60529.
Mounting
The KON-24 can be mounted in either vertical or horizontal
positions. Stress relief devices should be used to support cable
connections.

Construction features
Primary and secondary windings are assembled around a
toroidal core and attached to a support frame. For insulation and
protection, the assembly is cast in hydrophobic cycloaliphatic
epoxy resin (HCEP). The HCEP material offers superior arc track,
ozone, and ultraviolet-resistive properties while maintaining
physical strength. The hydrophobic surface properties of HCEP
ensure highly reliable performance in wet or humid environments.
Terminals
Primary terminals are electro-tin plated copper. Clamp-type
secondary terminals accommodate 2.5 mm2 through 25 mm2
wire.
