SynergEX EZFlex Encapsulated Hazardous Area Lighting and Heat Tracing Panelboards

Maximum safety, easy access and less downtime

Crouse-Hinds series SynergEX EZFlex panelboards provide overcurrent and short circuit protection for low voltage power, lighting and heat tracing applications in hazardous locations, such as refineries, chemical and petrochemical plants, mining, food processing facilities and corrosive and industrial processing facilities.

The new UL certified SynergEX EZFlex panel solution is now available with a unique patented EZFlex™ bus bar design that allows breaker interchangeability while providing the highest circuit count in the harsh and hazardous industry.

SynergEX EZFlex components and main breaker are fully encapsulated so that sparking or heat are not capable of igniting an explosive atmosphere.  These encapsulated components allow for the use of lightweight enclosures for easy installation. SynergEX panelboards open in seconds via two quarter-turn screws, versus up to 70+ bolts as with traditional NEMA 7 enclosures.
