Device and accessories

Device with a wide range of accessories

Holes for padlocks

Safety class CAT IV

!

EPPE PX



Measurement category CAT IV

CAT IV includes circuits which are connected directly to the source of power for a given building.

There are very high levels of available energy (e.g. limited only by the power transformer) and arc flash can occur.
