1 to 250 HP (0.75 to 185kW)
208, 240, 400, 480 or 590VAC
50 or 60 Hz (+10/-15%)
The MCH is designed to operate standard
polyphase induction motors rated for
200, 230, 400, 460 or 575VAC from 0 to 120Hz.
NEMA 1 is standard for drive & options
NEMA 12 available for drive only.
Easy set-up and operation: The MCH offers intuitive operator interface using plain English programming and operational information.
-2-line, 32 character backlit display
-Keypad with H-O-A operation

Motor Thermal Overload: The MCH includes UL and cUL approved motor protection device for single motor applications.
MCH Installed Options:
Pre-Engineered and factory installed, MCH options are "Contractor Ready" providing the following benefits:
Rugged steel enclosure with hinged cover
Plenty of knockouts that allow for top or bottom conduit runs.
Generous wire ways
Oversized terminal strip duplicates all the VFD terminals with plug connections that allow easy removal of the MCH Series without disturbing any field wiring.
Branch Circuit Protection:
Choose either a Circuit Breaker or Disconnect with fusing, both offer door interlocked rotary handle. If branch circuit protection is located elsewhere, door interlocked disconnect switch is available without fusing.
Input Line Reactor:
The most recommended complement to a good drive installation. The input reactor adds protection for the drive against common electrical noise and line spikes while reducing noise and harmonics back to the supply mains.
Three-contactor drive bypass completely isolates the drive when operating the motor at full speed directly across the line. Contactor logic and controls are operated at 115VAC and include pilot light operators and door mounted controls.
