612 PHOENIX CONTACT
This test is an electrical test to prove that
there are sufficient creepage distances.
To test that the distances between the
potentials of two neighboring terminal
blocks and between a terminal block and
the DIN rail are sufficient, an appropriate
test voltage is applied.
Rated insulation voltage (U
i
)
The r.m.s. or DC voltage value that is
permanently acceptable as a maximum
when correctly used.
The test voltage must be maintained for
over 60 seconds. The assignment illustrated
in the table is to be used as the basis for this.

No sparkover or disruptive discharge may
occur during testing. Creepage currents
must stay below 100 mA.

Test voltage = 1000 V + 2 x rated
insulation voltage U

Terminal blocks from Phoenix Contact
with a rated insulation voltage of 800 V
consistently pass the dielectric test with
2000 V~.

Surge voltage test
Proof of sufficiently large clearances
between two neighboring potentials is
provided by means of the surge voltage test.
The test is carried out with the surge
voltage five times at intervals of at least 1 s
for all polarities in relation to the rated
insulation voltage.
The distance between neighboring
terminal blocks or between the terminal
block and the rail is examined.
There must be no unintentional
sparkovers during the test.
Rated surge voltages for Phoenix Contact
terminal blocks are between 6 and 8 kV.
Operationally reliable use of the
documented operating voltages of the
terminal blocks is thereby effectively
confirmed.
