Bud’s NBF NEMA 4x Plastic Enclosure Offers Many Advantages

Published on: March 24, 2021 by Blair Haas

Among Bud’s broad offerings  in the area of NEMA 4x plastic enclosure, the NBF series is one of our most popular and it’s easy to see why.  With its all plastic construction (including hinges and latches) and with three material options it provides great flexibility for any application.  The materials are

  1. ABS plastic – perfect for applications that don’t require full certification but still need protection
  2. ABS/Polycarbonate blend – for those indoor installations in a more hazardous environment such as a factory floor or hose down situation
  3. Polycarbonate/PBT blend – with uv stabilization it is ideal for outdoor uses.

They also meet IP66 so they can withstand heavy sprays of water.  With snap-open latches for quick access and optional clear lids, optional bottom panels and included wall mounting hardware, we know that customer applications are in almost every possible industry from security to UV air quality filtration, from transformers to wi-fi and so many more.



The design leads to an endless opportunity to incorporate this type of enclosure into very different final products. Whether it is the NEMA 4x plastic enclosure ratings, its durability or the ability to easily modify the box, at Bud, we are always impressed with our customer’s ingenuity in creating devices using this series.  Sometimes, they even send in photos and descriptions, so we thought it might help your creative juices if we share a few of these with you.

An Emergency shut-off box

We use an NBF Box to house the emergency shutoff for our Powder Coating Line.  This NEMA 4x plastic enclosure was perfect for this application as it is easy to modify with the hole for the push-button and also to allow the components to stay dry and clean in an area with significant powder residue.
