Aging test
From the point of view of long lifecycles of
the terminal blocks, the aging behavior also
plays an important role.
In this test, the contact quality is verified by
means of simulated aging.
To simulate several years of use, five
terminal blocks are mounted horizontally
on a rail and connected in series using
conductors with the rated cross section.
Conductors with a minimum length of
300 mm are connected and the voltage
drop is measured on every terminal block.
The minimum temperature in the climate
cabinet is set to 20°C and the maximum
temperature to 85°C. During the heating
phase and the 10-minute pause phase with
maximum temperature, the rated current
flows. As a result, the maximum permissible
operating temperature of the test object
(130°C maximum) is reached. The cooling
down phase follows. The voltage drop is
always measured after 24 cycles in the
cooled down state (approximately 20°C).
The test consists of a total of 192 cycles.
The voltage drop must not exceed 3.2 mV
initially. During or after testing, it must not
exceed 4.8 mV or 1.5 times the value
measured after the 24th cycle.
Terminal blocks from Phoenix Contact
are designed for extreme durability even
under difficult temperature conditions.
Plastic as well as metal parts provide
sufficient safety reserves.

Corrosion test
The key role of the metal parts of
electrical connections becomes particularly
apparent in aggressive environments.
Corrosion-free contact areas are a
prerequisite for low-resistance and
therefore high-performance connections.
This test method describes a corrosion test
in condensation climates with an
atmosphere that contains sulfur dioxide.
Acidic compounds < Ph 7 form during the
test and attack the metal surfaces. Two
liters of distilled water and one liter of SO
2
gas are introduced into the test chamber. At
a test temperature of 40°C, sulfurous acid
forms during the test.
After eight hours of testing, the test
objects dry for 16 hours with the door
open. At the end of the test, the test
objects are visually inspected, and the
contact resistance is measured in order to
show the influence of this corrosion test on
the contact point in more detail. Phoenix
Contact terminal blocks create high-quality,
gas-tight connections that cannot be
impaired even by aggressive substances.
