In the right applications, variable frequency drives (VFD) will improve the control and reduce the energy costs of your AC motor-driven equipment. To install a VFD safely, however, you may need to reconsider the type of motor disconnect you use. The traditional knife-blade style of disconnect, while compliant with the National Electrical Code (NEC), is not the best choice for modern VFD applications. The reasons why are both physical and electrical.

If you need a compact power distribution solution for washdown or cleanroom use, check out our SpecMAXX Series. All enclosures feature a sloped roof that facilitates runoff of liquids and cleaning residue. A drainage channel impedes harborage of contaminants for use in a wide range of applications––from meat and dairy processing, to pharmaceutical plants. In addition to superior washdown performance, SpecMAXX also offers many custom design features.

Open any catalog of motor disconnect switches, and you may be overwhelmed by all the different design options. Does your disconnect need to be fusible? What is the best type of enclosure for your application? Is it a 1Ø or 3Ø switch requirement? What HP is needed? Do you need an installed pilot device?

Designing power distribution centers just got a whole lot easier. Our new web app helps you configure standard and custom AMAXX® power distribution centers in just a few mouse clicks. Watch the video to see it in action.
