LEGRAND’S range of fibreglass reinforced
polyester Marina cabinets, has been designed
for use in any environment, but these units are
particularly well suited for severe corrosive environ-
ments, including petrochemical, mining, general
engineering andmarine industries.
Marina enclosures are designed for maximum
safety and the ordered arrangement and optimum
protection of electrical components such as termi-
nal blocks, switches and sockets, fuse carriers, safety
transformers and circuit breakers.
Marina glass fibre reinforced polyester cabinets
are self-extinguishing at 960 °C and can withstand
temperature ratings of between -40 °C and 80 °C.
These cabinets have an IP66 index protection rating
for protection against dust and water and have
been adapted to withstand corrosive environments,
with excellent resistance to UV, saline mist, bases,
oils and greases.
Class II classificationmeets the requirements to
create suitable assemblies for photovoltaic instal-
lations.
Marina cabinets are available in sizes between
300 x 220 x 160 mm and 1 220 x 810 x 300 mm, all
fitted with a reversible door opening of 180° and
stainless steel hinge pins.
The cabinets are supplied with a set of internal
mounting accessories for easy and secure attach-
ment of equipment to the back of the cabinet. Ac-
cessories include double bar locks andmetal keys.
These fibreglass reinforced polyester cabinets
enhance Legrand’s range of stainless steel and
metal cabinets, which are manufactured according
to stringent quality specifications and are available
from Legrand and its carefully selected national
distributor network.

Fluke’s new ultra-rugged TL 175 TwistGuard test leads are
a world-first – featuring a manually adjustable guard. The
patented TwistGuard extendable tip shroud meets the highest
electrical safety requirements to reduce tip exposure while pro-
viding the versatility needed for most measurements. Simply
twisting the test lead cuts the exposed probe tip length from
19 to 4 mm. Extra-heavy duty strain relief on both probe-end
and plug-end has, remarkably, tested beyond 30 000 bends
without failure. WearGuard double insulated silicone leads
ensure added safety as each lead has two silicone insulation
layers: red or black on the outside and white inside. Any white
showing through warns of nicks or scuffs in the insulation.
The double insulation also means they can withstand high
temperatures and remain flexible in cold temperatures. The
leads are CAT II 1 000 V (extended) or CAT III 1 000 V and CAT IV
600 V safety rated (retracted).

THE newmulti-channel device
circuit breaker boards fromPhoenix
Contact are availablewith four,
eight, and 12 channels.
The boards are versatile as
they can be fitted individually
with thermos-magnetic or
electronic circuit breakers.
They are particularly suitable for
machine building and control and
process technology.
Due to the central potential
distribution, up to four loads can be protected per
channel.
This reduces installation time to aminimum, while
simultaneously saving space compared to conven-
tional installations. In addition to individual load
protection, the boards give you the option to loop in
safety-related relay contacts.
As such, the affected circuits are integrated into
the safety concept withminimal wiring. In doing so,
the switch contacts of the enabling current paths are
protected according to regulations. A supply of up
to 60 A can be achieved thanks to the high current
carrying capacity.
