Molded case circuit breakers
The PVGard MCCB by Eaton meets is designed for commercial and utility scale photovoltaic (PV) systems.
Eaton Corp. has introduced its line of molded case circuit breakers (MCCBs) designed for commercial and utility scale photovoltaic (PV) systems. Used in solar combiner and inverter applications, Eaton PVGard circuit breakers are rated up to 600 amp at 1000 Vdc. Eaton’s PVGard MCCB meets UL 489B, which requires rigorous testing to verify circuit protection that meets the specific requirements of PV systems. Eaton engineered the PVGard circuit breakers for the protection, switching, and isolation of PV systems up to 1000 Vdc. PVGard circuit breakers are reusable after clearing an electrical fault. Once the condition that created the fault is identified and repaired, the circuit breaker can simply be reset. They enable reductions in breaker, conductor, and enclosure sizes and can help promote potential cost savings.
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.
