Touch protection
Insulated cables and busbars
With insulated cables and busbars whose insulation extends inside the termination area of
the 3VA molded case circuit breaker, finger safety according to IP2X degree of protection is
achieved in IEC applications with the terminal cover. The requirements of NFPA 79
"Protection against electric shock" for UL applications are met with degree of protection
IP20. A basic precondition for this is proper installation.
Non-insulated cables and busbars
With non-insulated cables and busbars and bus connectors extended or bus connectors
offset, finger safety according to IP2X degree of protection is achieved in IEC applications
with terminal covers extended or offset. The requirements of NFPA 79 "Protection against
electric shock" for UL applications are met with degree of protection IP20. A basic
precondition for this is proper installation.
External wire connectors
External wire connectors are supplied as standard with a terminal cover extended. When a
terminal cover extended is used and properly installed, the external wire connectors achieve
finger safety according to IP2X degree of protection in IEC applications. The requirements of
NFPA 79 "Protection against electric shock" for UL applications are met with degree of
protection IP20.
