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.

Application: AC Drive for a Boat Lift
A boat lift is designed to store a boat out of the water when not in use and place it into the water when ready to be used. Typical applications include private boats stored adjacent to lakes, rivers, or canals. The system requires a Drive that can endure a harsh outdoor environment and contain inputs for limit switches. The drive must also be capable of operating when wired to a GFCI circuit, must be simple to operate, and it must also contain Pass Code Protection.
KB engineers selected model KBDA-27D with a custom Input/Output module. The drive is housed in a NEMA 4X enclosure which makes it suitable for outdoor use. It is rated for 1HP-3Ømotors and can operate from either a 115 or 230VAC line.
Custom software was developed by KB which incorporated the specifications required for the application:
A custom front label was developed which included the customer’s logo and special functions. In addition, the drive is factory programmed for Ready to Use, “Out-of-the-Box”. Read more Case Studies on our website.
GFCI’s will trip when used with most AC Drives. KB’s AC Drives contain special software to allow them to operate with GFCI circuits. This is a standard feature on our Digital AC Drives and optional, with factory programming, on all AC Hybrid Drives.
KB designs and manufactures more than 200 control models to serve the fractional to 5HP market. For standard controls, all sales must be processed through an authorized distributor. You can find a local distributor by using the locator on our website.
KB is the first manufacturer of variable frequency drives to apply the term “
A hybrid, by definition, is the merging of two technologies. The drive merges the digital technology of the microprocessor with an easy to use analog interface.
Simple trimpot adjustments and selectable jumpers are used in lieu of complicated programming.
Hybrid Drives, unlike Digital Drives, require less set up time and are easy to install and operate. Learn more about our Hybrid Drive products.
