Arc flash relay
The Littelfuse PGR-8800 arc-flash relay protects personnel and equipment by rapidly detecting developing arc-flash incidents and tripping the circuit before significant damage occurs.
The Littelfuse PGR-8800 arc-flash relay protects personnel and equipment by rapidly detecting developing arc-flash incidents and tripping the circuit before significant damage occurs. This relay can detect an arc flash in less than 1 msec, and it detects both current and light to minimize nuisance trips and to provide overcurrent protection. The compact, stand-alone unit features up to 24 light sensors, including optional fiber-optic cable sensors that can protect difficult-to-reach compartments. The relay offers adjustable light level and wide-angle detection, built-in LED to indicate local sensor health or trip state, and application tool s to help determine sensor placement and maintenance schedules.
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.
