NEMA 1 enclosure versus a NEMA 4X enclosure?

KB Electronics, Inc. Manufacturer of AC Drives, DC Drives & Variable Speed Controls

 What is the difference between a KB Drive with a NEMA 1 enclosure and a NEMA 4X enclosure?

NEMA enclosures, in general, are designed to prevent electrical shock by protecting the user from incidental contact with the components contained within.

KB’s NEMA 1 drives provide a degree of protection against falling dirt. They are equipped with knockouts for standard electrical fittings.

KB’s NEMA 4X drives are constructed with a rugged die-cast aluminum enclosure with a hinged cover. They offer watertight integrity, which makes them ideal for harsh washdown indoor or outdoor applications. They are equipped for use with liquidtight electrical fittings.
