Enclosure Types

The Class 8839 58M Enclosed AC drives are available in Type 1, Type 1G, or Type 12 enclosures. If Type 3R, 4, or 4X enclosures are required, consult product support or customer service for enclosed drives.

Outside installations requiring drives should be quoted for installation in climate controlled Type 3R walk-in enclosures available separately from our Power Zone Center group in Smyrna, TN.

Application Information

Relay Contact Ratings

Interposing relay contacts are available for customer use. Contacts are available for run and fault indication as standard. Optional contacts (if selected) provide indication of bypass on, auto mode, and communication mode. Relay contacts are rated for switching inductive loads and have a 5 A continuous current rating.
