M-Flex enclosed drive controllers are available in Type 1 general purpose or Type 12/12K drip-/dust-proof enclosures in integrated or barriered designs.

Integrated enclosures can be wall or floor mounted, depending on size. They provide a circuit breaker disconnect and enough room for power peripherals, including isolation and bypass contactors, all within the same enclosure. Barriered enclosures separate power and control circuits, such as bypass, from drive control. The separate compartments allow for maximum flexibility if servicing a drive in bypass operation.
