Powerful PV overvoltage
protection
The new VAL-MB product family from Phoenix
Contact provides powerful and compact pro-
tective devices for photovoltaic applications
with generator voltages of up to 1 500 Vdc.The
protective devices are specially adapted to dc
application require-
ments and certified
by KEMA.
Longer inlet fun-
n e l s a nd h i gh e r
screw shafts provide
additional protec-
tion against arcing.
The product range
includes protective
devices for generator
voltages of 600Vdc, 1 000Vdc and 1 500Vdc, as
type-1/2 lightning current arresters, as well as
pure type 2 surge protection devices. Variants
are available with or without remote signaling
contact. All protective devices have a short-circuit
protection of 2 000 A and can also be used in
high-altitude plants up to 6000 meters in altitude.

Durable and powerful type-1 lightning current arrester
The Flashtrab SEC-PLUS type-1 lightning current arresters from Phoenix Contact,
which are particularly durable and powerful thanks to Safe Energy ControlTechnol-
ogy, have just been com-
plemented by two product
variants. The Flashtrab
SEC-PLUS 440 product
variant is particularly suit-
ed to special industrial ap-
plications with 440/690 V
networks or 400 V power
supply systems.The prod-
ucts impress with their
strong shock and vibration
resistance. This compact
variant can be used up to
400Awithout an additional back-up fuse.The Flashtrab SEC-PLUS 350 variant is used
in the pre-metering area of the main feed, or in industrial applications. High voltage
fluctuations and lightning current loads are no problem for the type-1 arrester.The
good protection level and backup fuse-free use up to 315 A deliver additional ad-
vantages. Both variants are pluggable and can be tested with the CheckMaster 2 test
instrument for surge protection devices. Like any other SEC family type-1 arrester, the
Flashtrab SEC-PLUS devices are also type-2 arrester tested and certified.The protec-
tive devices of the SEC product family have been completely redeveloped and are
based on Safe Energy ControlTechnology (SEC).The spark gap safely prevents any
power supply secondary current.This means that the load of the entire installation
is reduced to a minimum in the event of a lightning event.
