HOUSTON, October 11, 2010 – Cooper Industries plc (NYSE: CBE), a global provider of electrical products and solutions, today announced it will exhibit its solar mounting and wiring, power management, and circuit management and protection solutions at Solar Power International 2010, October 12-14, at the Los Angeles Convention Center. Building on its history of expertise and innovation, Cooper Industries develops solutions that fulfill complete balance of system needs, helping to decrease overall installation and ongoing maintenance costs of solar systems. Multiple Cooper divisions, including Cooper B-Line, Cooper Bussmann, Cooper Crouse-Hinds and Cooper Power Systems, will showcase Cooper’s range of solar products at Solar Power International, Booth #1120. As Cooper’s latest solar offering, Cooper Bussmann will introduce its new Surge Protective Device (SPD) at the event. The first UL1449 3rd edition recognized Surge Protective Device for solar applications, Cooper Bussmann’s new SPD is simple to identify, install and maintain. Built-in, fast-acting short-circuit interruption technology for 600Vdc, 1000Vdc and 1200Vdc systems safely shunts damaging surges and overvoltages to ground. This high performance capability also eliminates the need for additional fuses or overcurrent protection, wiring and panel space, providing PV users complete protection at substantial cost savings. Cooper B-Line will additionally showcase its new ARISTATM commercial rooftop mounting system. This cost-effective and easy to install solar PV mounting system features standard electrical components and no loose hardware. The ARISTA system’s pre-assembled frames effectively angle solar PV panels in the optimal position for maximum performance. With a high degree of flexibility, the ARISTA system -More- Cooper Industries – Page 2 can be used for landscape or portrait mounting of PV panels for both ballasted and positively tied solutions. In addition to ARISTA, Cooper B-Line offers a comprehensive set of custom engineered solutions for mounting solar PV panels in ground, commercial roof and open-structure applications. "Cooper Industries’ commitment to innovation and expertise remains particularly evident in the growing solar energy sector,” explained Cooper Industries CEO Kirk Hachigian. “New products like our surge protection devices and solar commercial rooftop mounting system come not only as a result of extensive research and development, but of our continued anticipation of customers’ evolving needs.” In addition to Cooper Industries’ latest products, a variety of solutions comprise Cooper’s balance of system offerings, including combiner boxes. Available from both Cooper Bussmann and Cooper Crouse-Hinds, combiner boxes provide the housing to combine and connect the conductors from several arrays or solar panels into one main buss or feed. For larger commercial and utility-scale projects, Cooper Power Systems reliably and efficiently delivers power to the utility grid. Cooper Power Systems offers high efficiency solar GSU transformers, cooled with Envirotemp FR3 soy oil-based dielectric fluid; specially designed with inverter technology and energy harvest in mind. In addition to medium-voltage transformers, a full line of molded rubber parts and substation products such as capacitors, arresters, relays, switchgear, and automation communication systems ensure that the quality of the electricity generated meets the grid interconnection requirements. For remote applications, solar kits from Cooper Crouse-Hinds eliminate the need for expensive utility power investments. Solar kits are installed in weatherproof enclosures to withstand harsh weather conditions and high wind loads. Solar Power International, previously called Solar Power Conference and Expo, was created in 2004 when the Solar Electric Power Association (SEPA) and the Solar Energy Industries Association (SEIA) joined together to form a North American business-to-business solar conference and expo. Representatives from Cooper Industries and its divisions will be on hand throughout Solar Power International 2010.
