Class 8839 58M Enclosed AC Drive Ratings

Class 8839 58M Enclosed AC drives are available at:

•1–500 hp VT, 1–75 hp CT, @ 460 Vac and

•1–50 hp VT, 1–40 hp CT, @ 208/230 Vac

•Consult Drives Product Support for CT ratings above 75 hp.

Standard and Engineered Options

Two option categories (Standard and E-Mods) allow Square D to balance customer requirements for cost effective, fast turn around orders with complex, highly engineered, customized motor control solutions. Standard options are pre-engineered and well defined with selection rules. Orders with standard options are supported by an automated drawing process which produces electronically generated “as built” customer documentation.

E-Mods (engineering options) require additional engineering effort to layout, define interoperability, and develop custom customer and manufacturing documentation. Standard enclosure dimensions may not apply to orders containing E-Mods. Orders containing E-Mods will have increased lead times.
