Carrying out a dimensional check of
clearances and creepage distances confirms
that electrical insulation properties are
adequate with respect to the following:
– Application
– Expected pollution
– Ambient conditions
The minimum distances are defined in
IEC 60947-1 and UL 1059.
The distance is verified by measuring
between two neighboring terminal blocks and
the support, taking into account the shortest
distances.
For the clearance, this means:
It is the shortest distance in the air between
two conductive parts. The deciding factors for
rating the minimum clearance values are the
rated surge voltage and the surge voltage
category of the terminal block.
For the creepage distances, this
means:
It is the shortest distance along the
insulating body between two conductive
parts. The deciding factors for determining
the minimum creepage distance are the
rated voltage, the pollution degree, and the
insulation material group of the terminal
block.
The minimum values can be taken from the
tables of the relevant standards.
IEC 60947-7-1
Phoenix Contact terminal blocks are
designed with surge voltage category III and
pollution degree 3 with the required
distances.
UL 1059
Phoenix Contact terminal blocks are
generally designed for a nominal voltage of
600 V in Use Group C.

data sheets or the catalog documentation.
