Arc flash protection
Arc Guard TVOC-2 by ABB
Arc Guard TVOC-2 by ABB features upgrades and functions to provide arc flash protection, detecting faults in low- and medium-voltage switchgear and disconnecting the power provided to the arc within 30 to 50 milliseconds, preventing serious injury to personnel and damage to expensive equipment. Without the Arc Guard System, an arc flash will typically trip a circuit breaker in approximately one sec, enough time for the arc to destroy the switchgear and kill or seriously injure a person. TVOC-2 is now UL listed, and when installed along with ABB’s Emax circuit breakers, carries a functional safety rating of SIL-2. The SIL-2 certification confirms that the TVOC-2 has achieved the standard required to protect both humans and equipment.

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.
