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.
