Model 90

Model 90 MCCs are legacy Siemens units built for standard motor control. These systems used NEMA starters and traditional wiring schemes. While no longer manufactured, they remain in use across many industrial plants and building systems.

AmpState retrofits Model 90 MCCs with upgraded contactors, breakers, and overload relays. We also provide retrofit buckets and can splice modern tiastar lineups to Model 90 enclosures for seamless modernization without full replacement.
