PV, wind power generation fuses
Cooper Bussmann has expanded its CUBEFuse portfolio of Class CF fuses for protecting solar and wind power generation installations.
Cooper Bussmann has expanded its CUBEFuse portfolio of Class CF fuses for protecting solar and wind power generation installations. The finger-safe CUBEFuse design delivers the benefits of up to an 80% smaller footprint compared to other fuse solutions while limiting exposure to live parts for increased safety. Listed to UL 2579, the PVCF photovoltaic (PV) version withstands extreme temperature cycling conditions ranging from -40 F through 90 C. It is designed to protect PV cell arrays by responding quickly to the lower fault current levels encountered in solar installations. Recognized to UL 248, the fast-acting WCF wind power version is specially rated at 690 Vac and available in ampacities from 1 to 100 amps along with special 30-, 60-, or 100-amp 690 V rated ampacity-rejecting holders that help prevent overfusing. With current-limiting Class J electrical performance, the wind power CUBEFuse increases electrical safety by reducing arc flash hazard levels.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
