Let's start with the official definition of NEMA 3R (taken from nema.org):

Type 3R  Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure.

If you are looking for a NEMA 3R enclosure or drive package, Marshall Wolf Automation can make it easy!

I'm working on a special 4th of July e-newsletter focusing on all of our product lines that are Made in the USA (interested in receiving it? Sign up here!).

Anyway, I was looking online for interesting facts to include in the newsletter and came across this interesting promotion from Hardee's.

Basically on the 4th of July, the first 50 people to arrive at each store dressed as Spiderman (yes, Spiderman!) will receive a free Grilled Cheese Bacon Thickburger™. Brilliant social media marketing plan!

I was recently updating some of our Saginaw industrial enclosures and noticed a few series of junction enclosures on the list.

I had never heard of a junction enclosures so I headed back to my trusted resource, Wikipedia:

'An electrical junction box is a container for electrical connections, usually intended to conceal them from sight and meter tampering. A small metal or plastic junction box may form part of an electrical conduit wiring system in a building, or may be buried in the plaster of a wall, concealed behind an access panel or cast into concrete with only the lid showing.'

Basically I think it's an enclosure used to hide everything inside, however, we do offer them with windows as well. I'm guessing so you can see LED okay indicators? 

Anyway, we now have junction enclosures, a.k.a. junction boxes, on our website.
