Insulated cables and busbars
With insulated cables and busbars that have insulation that reaches inside the termination
area of the 3VA molded case circuit breaker, the unit is classed as finger-safe (IP2X) if it is
also equipped with a terminal cover. This protection is guaranteed only if the unit is installed
and wired correctly.
Non-insulated cables and busbars
With non-insulated cables and busbars, and bus connectors extended or bus connectors
offset, the unit is classed as finger-safe (IP2X) if it is also equipped with an extended or
offset terminal cover. This protection is guaranteed only if the unit is installed and wired
correctly.
External wire connectors are supplied as standard with a terminal cover extended. The
external wire connectors are classed as finger-safe (IP2X) on condition that the extended
terminal cover is correctly installed.
