The maximum standard amperage ratings range of the Square D Powerpact R-frame molded case circuit breakers has been extended to 3,000 A. With the range extension, the R-frame breakers can replace more bulky, insulated case breakers, providing users more flexibility with a smaller footprint. For panel builders and electrical distribution equipment manufacturers, the unit-mounted Powerpact R-frame breakers can fit a variety of applications, including main service, feeders and high-current branches. Also suitable for panels and other equipment requiring high currents such as back-up power, generators and HVAC, the R-frame circuit breakers are offered with 80% and 100% ratings with interrupting ratings of 35 kA, 65 kA and 100 kA at 480 Vac. They include the RL3TB terminal kits for bussing or optional cable lugs. The breakers are available in unit-mount models, with ratings from 600 A to 3,000 A, and I-line models up to 1,200 A. Powerpact R-frame circuit breakers include Micrologic trip unit technology that facilitates Modbus communication interface, power metering and harmonic analysis.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
