Our safety connection system
the new generation of piLZ
®
heating mantles offers the operator optimal protection during day-to-day operation thanks to our combinable safety connection system.
as a rule all piLZ
®
heating mantles (laboratory heating mantles) are equipped with a multipole plug.

The heating mantles are connected to the mains supply network via a suitable connection system that plugs into a grounded socket (Schuko).
the
WHZa 1000
residual current device (RCD) is connected to the PILZ heating mantle via a multipole coupling as a standard (Fig. 4).
If the RCD is not required because the heating mantle is operated on a protected circuit (e.g. in a laboratory), the PILZ
®
heating mantle may also be connected directly
to the supply network via the
WHZa 2000
Schuko plug (Fig. 5, optional accessory).
