Constant commitment
to quality and service
(Formerly as Ferraz Shawmut, from now on as Mersen)
Mersen, formerly Ferraz Shawmut is the world’s
reference in circuit protection. Our products and the
services we offer with them, have a well-earned
reputation for quality. The fuses, surge arresters and
other products in the HelioProtection® program have
been specially designed and tested to serve as safety
elements in solar power systems. They guarantee
failure-free operation of that equipment with no
secondary effects. Not only is Mersen constantly on
top of the requirements in standards and attentive to
the demands of both users and professionals in terms
of reliability, maintainability, availability and safety, the
company voluntarily subjects itself to strict quality
monitoring backed up by extensive electrical,
mechanical and climatic tests.
Two labs dedicated to quality
The proof of that quest for continual improvement:
a total of more than a million tests in 25 years!
Mersen has two test labs: one in Newburyport,
Massachusetts, and one in Saint Bonnet de Mure
in France. The two are complementary, in terms
of the available resources, to be able to offer
the widest possible range of a.c. and d.c. tests
to UL-CSA and IEC standards.
Saint-Bonnet-de-Mure:
• temperature rise and strength tests on
test benches with extra low voltage power supply;
• short circuit withstand tests (400MVA generator);
• d.c. tests with large time constants;
• dielectric tests at industrial frequencies;
• faraday cage impulse voltage tests;
• oven climate tests from -45°C to +150°C,
plus salt mist;
• mechanical tests, pressure, vibration,
acceleration - and more.

Going even
further together
To support all those we work with - developers, designers,
engineering consultants, purchasers, quality managers,
qualification inspectors, insurance companies, rating
and listing agencies - in their efforts to specify, design,
build, test and run solar power systems, Mersen has
invested in the necessary resources:
• a qualified design department to help with the most
complex and arduous projects and get involved
in co-design or co-development initiatives;
• a technical support department with
attentive engineering staff listening
to other professionals and helping
them match protection components
or solutions to their equipment;
• a hotline at +33 4 26 29 29 29;
• a Web site entirely devoted to PV
at www.helioprotection.com.
Newburyport:
• a specialized d.c. lab - obviously an asset
in designing fuses for photovoltaic applications;
• a low power test lab;
• fusion tests at 0 to 6000A constant current;
• simulations of equipment starting up and stopping
from 0 to 3000A;
• a low voltage test bench for surge protective devices;
• temperature tests, etc.
Mersen welcomes
customers at both
locations to run test
campaigns focused
on critical points in
their own bills of
requirements.

Residential
(5 to 36kW)
Your solar partner
Mersen has always been a partner
for electrical equipment distributors,
and has played a role ever since
solar power started to boom on the
residential market, i.e. for private
homes, small apartment buildings
and farm buildings.
Our HelioProtection® range is now
widely available from distributors.
Electrical contractors can choose
from a wide range of products
designed especially for solar power.
For them, our product offering
is a basis in recommending
a system that meets the user’s
needs - reliable, with a fast return
on investment and sized
appropriately - and obeys the very
strict safety standards that are
specific to photovoltaics.
Return on investment
for a typical 3 kWc system
A solar panel is designed to produce
for about 20 years. With enough
sunshine available, it can easily pay
itself off in 6 to 10 years. A 25m² solar
array can generate up to 3500kWh
per year, i.e. what an average
household consumes.
A PV system can easily be built into
your residential construction project
and complements measures
to improve energy performance
and build “zero energy homes”,
where power consumption is equal
to power generation.

The walls and roofs of buildings
- office towers, factories, malls
and warehouses - are among the
preferred supports for solar power
systems. Architects, promoters
and developers have grasped
the importance of this energy
revolution, and more and more
of them are recommending such
solutions.
Those specifiers, as well as major
electrical contractors, can count on
Mersen’s sales engineers, market
managers, technical support and
distribution network to set up
systems to order, with a wide
variety of architectures and central
control systems on offer.
For large-scale projects, our Design
department can propose a package
of products and services to match
the customer’s specifications, which
often interest insurance companies
directly, given the specific
standards that govern solar power
(UTE C15-712 guidelines,
NFC15-100 C13-100 and C14-00).
Solar Future
“In the long term
it is estimated that solar power
could contribute to an increasing
part of the total energy consumption…
In 2030, photovoltaic could produce
enough energy to supply electricity
to 3.7 million people globally.”

Guaranteed protection,
from the cell to the grid
The fact that a solar device is both a d.c. environment and a non interruptible
source of current whenever the sun is shining makes things pretty
complicated compared to our customary a.c. world. Ensuring the safety
of solar power generating facilities is a tricky business, because there are
very specific risks inherent to this kind of electrical equipment.
So compliance with standards and recommendations is critical
to guaranteeing the safety of people and property.

Recommendations
• Do not operate under load.
• The PV source must be connected
to the upstream terminal.
• Non insulated conductive parts:
preferably the equipment should be
laid out keeping the + and - polarities
separate.
• Mounting with SPD: check that the
SPD’ Up is compatible with the US10’s
IU imp=6kV (see UTE C15-712).

HelioProtection®
Switch
Benefits
Our products are typically used
as switch of isolation on a chain group
of solar panels, or as main switch
on a system of solar panels arriving
at the inverter.
They are compact, the poles are already
in series and they are delivered
with padlockable handle and
accessories for isolation of upstream
and downstream connections.
To allow to cut the tension
of 1000VDC it is indispensable
to put 6 poles in series
in the installation.
The upstream and downstream
connections are downward
to facilitate the connecting,
and avoid the exits upward
the cubicle (waterproofness
problem).

DC contactors
In solar farms for power generation many inverters can operate,
simultaneously or not. Connecting different solar panels to different inverters
should be useful (commute from one inverter to an other, optimize power
generation especially in case of low shine level).
Commuting DC voltages in the range 500V up to 1500V is necessary.
The Lenoir-Elec branded modular contactors of Mersen are part
of our HelioProtection® program. They are particularly well fitted to this application.
