San Francisco, CA, July 9-11, 2013

NEWBURYPORT, Mass. (July 1, 2013) — Mersen, a global leader in the field of electrical protection, will display

its solar power solutions at Intersolar 2013 in San Francisco, CA, July 9-11, 2013.
As the market for solar energy continues to grow, the technology and equipment used to harness and distribute
photovoltaic power continues to evolve. Over the past several years, Mersen has invested countless resources,
expertise, and initiative contributing toward developing the proper codes, standards, and products mandated by
the solar power industry.

Recent innovations developed by Mersen include:

· USGM-HEL Fuseholders are equipped with industry-proven and patented CAGE CLAMP® technology.
Mersen is the first manufacturer to offer this technology in a power fuseholder. This screw-less, spring
pressure, wire termination technology has over 25 years of field experience and acceptance and can
reduce wire installation time and cost by up to 75%. CAGE CLAMP technology significantly improves
system reliability by maintaining a very low contact resistance easily withstanding corrosion, vibration, and
temperature cycling. The technology also eliminates the need for routine torque maintenance required by
standard screw-type terminations.

· HelioProtection fuse line, the industry's first UL 2579 listed range of dedicated photovoltaic fuses,
provides superior overcurrent protection at the combiner box and inverter levels and covers applications
ranging from 1 to 400A, up to 1500VDC. The enhanced fuse construction of the HelioProtection series
makes it ideal for continuous temperature and current cycling withstand adding to system longevity. Low
minimum breaking capacity capabilities of 1.35 times the fuse-rated current value allow for safe circuit
interruption under typical low-fault current conditions produced by PV arrays. The HelioProtection fuse
line includes the HP6M, HP10M, HP15M, HP6J, HP10J, HP10NH and HP15NH series.

· PV String Monitoring Solution: In mid- and large-scale photovoltaic (PV) installations, it is mandatory to
properly monitor the string level production over time to guarantee long term power performance by
maximizing energy production, optimizing facility management, and decreasing operations and
maintenance costs. Mersen delivers a string monitoring solution to be installed in the string combiner box.

· Surge-Trap Modular and Pluggable Surge Protective Devices (SPDs) are specifically designed with
the photovoltaic industry in mind. Surge-Trap Modular and Pluggable SPDs are DIN-rail mountable and
feature Mersen's patented TPMOV® technology inside. No additional overcurrent protection required.

Featured Product

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer

HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
