SynergEX Encapsulated Hazardous Area Lighting and Heat Tracing Panelboards

Maximum safety, easy access and less downtime

Crouse-Hinds series SynergEX 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 ETL certified SynergEX panelboard features optional integrated terminal blocks or fuse holders, enhancing safety, space efficiency, cost savings, ease of maintenance, system reliability as well as simplifying wiring and troubleshooting in the field.  The design ensures a more compact, organized, and reliable electrical system, making it an ideal choice for industrial applications.

SynergEX 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 a single lockable handle, versus up to 70+ bolts as with traditional NEMA 7 enclosures.
