Motor protection relays
Finalist in Equipment Level Sensors and Controls in Consulting-Specifying Engineer's 2011 Product of the Year competition
The PGR-6150 motor protection relay system from Littelfuse provides current- and temperature-based protection, metering, and data logging. The system is designed for low- to medium-horsepower three-phase motors in industrial environments and protects against overload, undercurrent, overcurrent, jam, overheating, phase loss, phase reverse, and phase unbalance. There are 13 protective functions that reduce or eliminate damage caused by electrical faults based on current and temperature inputs. The optional operator interface allows remote operation and field programming, and displays metered values. The product has a compact footprint and integrated current transformers. The wide adjustment range can accommodate different motor sizes and applications.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
