Eaton’s First Motor Control Centre Technology Incorporates Arc Flash Prevention

May 4 2016

Eaton’s new, arc-resistant version of its FlashGard motor control centre technology is designed to prevent an arc flash event and protect personnel if an arc flash occurs. Eaton is the first manufacturer to combine arc-preventative and arc-resistant technology within a single motor control centre.

The solution is designed to emphasize prevention, insulation and isolation to support safety during routine maintenance operations in oil and gas, water and wastewater, mining and other industrial applications.

“Eaton’s new FlashGard arc-resistant MCC builds on nearly a decade of more than 10,000 installations and is designed to establish new levels of protection for personnel and equipment in a wide range of new and retrofit industrial applications,” says Glynn Newby, product manager at Eaton. “The innovative technology is one of more than 55 Eaton solutions designed to help prevent arc-flash hazards.”

Eaton’s patented FlashGard design enables units to be disconnected and reconnected to the vertical bus with the unit door closed; maintaining a dead-front barrier during maintenance operations helps enhance operator safety. The solution also incorporates Eaton’s industry-first RotoTrack racking mechanism, which is designed to provide bus isolation, stab indication and lockout features to proactively prevent the initiation of an arc flash event.

The new FlashGard arc-resistant MCC is engineered to provide the added benefit of National Electrical Manufacturers Association (NEMA) Type 2 arc-resistant construction, meaning that arc resistant designs or features are present on the front, back, and sides of the assembly. This Type 2 rating translates to enhanced safety around the entire perimeter of the MCC should an arc flash event occur.

The FlashGard arc-resistant MCC is tested and verified per the criteria found in the Institute of Electrical and Electronics Engineers (IEEE) guideline C37.20.7 and Canadian Standards Association (CSA) standard C22.2 No. 0.22-11. It is also Underwriters Laboratory (UL) UL845 approved. The solution is available for three-phase, 230-volt applications up to 300 horsepower, or three-phase, 480-volt applications up to 600 horsepower.
