The commiTmenT of mersen in safer and more reliable solar phoTovolTaic insTallaTions
In the solar market more especially, Mersen is a driving force in the development of safer and more reliable solar photovoltaic installations.To participate in implementing such installations, Mersen has developed a special program of solutions branded HelioProtection®.
HelioProtection® program is a mix of:
• dedication – all the solutions have been designed for the specific solar photovoltaic applications.
• Innovation – the solutions in this program are all on the technological edge.
• expertise – this program is supported in the marketplace by a team of Mersen’s experts for helping the customer to select and apply the proper solution.
HelioProtection® is a brand of Mersen, the new name of Ferraz Shawmut.

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.

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.
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.

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 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.
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.

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.”European Photovoltaic

GuaranTeed proTecTion,from The cell To The GridThe 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.

pv fire shunT
The PV Fire Shunt expands the HelioProtection® program, with a product designed for the residential PV solar market.It is intended to help firefighters and emergency responders called to a residential fire at a house equipped with a PV system.The technology employed (a shunt that lowers voltage to almost 0V when the handle is pulled) and the product’s mechanical characteristics (materials guaranteeing good resistance to fire and flames) mean a safer working environment with no electrical hazard.It can shunt up to 3 strings of solar modules using a pike pole (routine equipment for firefighters) from the ground level.

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).
AccessoriesSame as the entire Modulostar® range.
Characteristics• Wiring: rigid wire = 1 - 16mm2 (18-6AWG),
flexible wire = 0.75 - 10mm2 (18-8AWG) use 75°C wire CO only.
• Screw driver heads: Mersen recommends use of PZ 2 or flat 5.5x1mm heads (maximum diameter 6mm).
• Maximum tightening torque: 2.2Nm• DC20B-IP2X.

Finger Safe Power Distribution Blocks bring extra safety to solar power systems.They can be snapped onto DIN rails and are IP20 finger safe (as per IEC standard 529). Starting from a primary pole, each FSPDB can distribute power to several secondary ones: 1, 4 or 8 depending on the model. Several FSPDBs can be combined to form a multipole distribution point.With the 175A to 800A FSPDB line, wiring from 2.5 to 300mm2 (aluminum or copper) can be used for connections. These products are UL Recognized.

Technical Data According to IEC 60947 for IT Switch-Disconnectors
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.
All our HelioProtection® switch are equipped with guaranteed shunts providing time savings in the mounting process.
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).

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 The Mersen modular contactors modular contactors are part of our HelioProtection® program. They are particularly well fitted to this application.
For large solar power applications at Mersen’s we have the abilities to design and manufacture custom enclosures as per customer specifications.Supplying railway, utilities, power conversion markets, the company has the resources to design and manufacture high-power cubicles.
