Black Box Explains...NEMA ratings for enclosures.

The National Electrical Manufacturers’ Association (NEMA) issues guidelines and ratings for an enclosure’s level of protection against contaminants that might come in contact with its enclosed equipment.

There are many numerical... more/see it nowNEMA designations; we’ll discuss NEMA enclosures relevant to our on-line catalog: NEMA 3, NEMA 3R, NEMA 4, NEMA 4X, and NEMA 12.

NEMA 3 enclosures, designed for both indoor and outdoor use, provide protection against falling dirt, windblown dust, rain, sleet, and snow, as well as ice formation.

The NEMA 3R rating is identical to NEMA 3 except that it doesn’t specify protection against windblown dust.

NEMA 4 and 4X enclosures, also designed for indoor and outdoor use, protect against windblown dust and rain, splashing and hose-directed water, and ice formation. NEMA 4X goes further than NEMA 4, specifying that the enclosure will also protect against corrosion caused by the elements.

NEMA 12 enclosures are constructed for indoor use only and are designed to provide protection against falling dirt, circulating dust, lint, fibers, and dripping or splashing noncorrosive liquids. Protection against oil and coolant seepage is also a prerequisite for NEMA 12 designation. collapse

Black Box Explains...10-32, 12-24, and M6 rails.

The rails on cabinets and racks typically come with one of three mounting options: 10-32, 12-24, or M6.

The 10-32 and 12-24 options are round holes found on drilled and tapped... more/see it nowrails. You’ll find 10-32 openings on cabinets, while 12-24 holes are more commonly found on relay racks and frames. However, exceptions do exist. It’s very important to find out which type of mounting option your equipment requires before you order a cabinet or rack.

M6 holes are square, rather than round. M6 rails were developed to hold rackmount equipment, and you will find them on most server cabinets.

What makes M6 rails so popular on server cabinets? They’re adaptable. With just one cage nut, you can change a square hole into a round one. That gives you much more versatility in your equipment and mounting choices.

If you have a wide array of equipment, such as rackmount servers, hubs, routers, and patch panels, your best bet is a cabinet with M6 rails. It will accommodate the rackmount servers, and the other equipment can be mounted on those same rails using cage nuts.

If you’re unsure what type of cabinet, rack, or frame is best for your application, contact the experts at Black Box Tech Support. They’ll be glad to help you find the right enclosure for your equipment. collapse
