APPLICATION
These enclosures are used in harsh industrial environments to
house large components such as motor starters, drives, contactors
and PLCs as well as a wide range of other electrical and electric
equipment. A modular interior rail system (PROLINE) provides an
extensive range of mounting options. Whether your application
calls for rack mounting, panel mounting or grid system mounting, a
combination of PROLINE components can deliver the right solution
for ultimate equipment mounting flexibility and convenience. Three-
point latching and sealing provide industry-leading protection from
dust, oil and water. The FS66S enclosures are used extensively
in oil and gas, water/wastewater, petrochemical and power
plant environments and offer a perfect solution to outdoor DCS
applications.
Four styles are available to provide maximum flexibility:
1. One-Door Single-Access Enclosures (single door on front)
2. One-Door Dual-Access Enclosures (single door on front and
rear)
3. Two-Door Single-Access Enclosures (doors close on a
removable centerpost)
4. Two-Door Dual-Access Enclosures (doors close on a
removable centerpost on front and rear)
Each style is also offered in 304 or 316L stainless steel, and can
be manufactured as standard duty (14 gauge) and heavy duty (12
gauge).
