Rittal Stainless Steel Enclosures

Stainless steel enclosures There are two types of stainless steel commonly found in the fabrication of enclosures. Type 304 stainless steel contains 18% chromium and 8% nickel. While it prevents corrosion in most conditions, it does not perform well in high saline environments. Type 316 stainless steel contains 16% chromium, 10% nickel and 2% molybdenum. This is a higher grade of stainless steel and withstands chemical and saline exposure. Some of the advantages of using stainless steel for electrical enclosures are that they have a high resistance to corrosion and function well in extreme temperatures. They are also easy to fabricate and sanitize. Most stainless steel enclosures are NEMA 4X rated which indicates that they protect equipment from damaging environmental conditions such as rain, ice formation and dirt. Stainless steel enclosures are commonly found in water treatment facilities, marine environments, oil and gas industries and industrial food processing.
Rittal Stainless Steel Enclosures are manufactured from a single piece of cold-rolled Type 304 or Type 316 stainless steel. The multi-fold process provides additional strength and stability. They have a knife edge flange trough collar to divert liquids, dirt and dust rating a NEMA Type 4. All Rittal wall mount enclosures and junction boxes include a zinc galvanized wall mounting panel and come with a quarter-turn latch. The gasket on the doors are foamed in place for a proper seal.
All Rittal stainless steel enclosures (wall mount enclosures and junction boxes) are made from 316 stainless steel. Every Rittal wall mount enclosures include a zinc galvanized mounting panel. With the one-piece, welded, cold-rolled stainless-steel body and a door with foam gasketing they provide a water and dust proof environmental seal qualifying these cabinets with a NEMA 4X rating.
Rittal designed their wall-mount, stainless steel enclosures with rear, blind nuts to be mounted to the wall and maintain the integrity of the NEMA 4X rating. All Rittal slope top enclosures have a 20° sloped roof overhanging the door.
The Rittal stainless steel WM (wall mount) series range in size from 12” x 12” x 6” to 60” x 36” x 16”, while the Rittal stainless steel JB (junction box) series start at 6” x 6” x 4” and go up to 16” x 14” x 8”.
