Three-Phase, Type MD, 60 Hz
Type MD
m Suitable for indoor or outdoorapplications (with weathershield)
m Ventilated enclosuresm 220°C Insulation system, 150°C Rise
standard (self extinguishing)H Available in ratings from
7.5 through 1500kVA
Application DescriptionDrive isolation transformers are specif-ically designed for use with AC and DCadjustable speed drives. Two windingdrive isolation transformers provide:
• Electrical isolation between theincoming line and the drive circuitry
m Voltage conversion of input line tostandard drive input voltages
m Minimized line disturbances causedby SCR (silicon controlled rectifiers)firing
• Reduced short circuit currents andvoltage line transients
Drive isolation transformers are specif-ically sized to the drive kVA require-ments and are braced to withstand themechanical stresses of current rever-sals and short circuits associated withSCR drives.
Features, Benefitsand Functions• UL Listed• 60 Hz operation
(50/60 Hz operation available)m Short-term overload capability as
required by ANSI3 Primary and secondary terminals
are front accessible for fast and easyconnection
H Slotted screw mounting holes inenclosure and cover reduce installa-tion time
m Sound dampening pads, whichisolate the core and coil from thecase, reduce noise levels to meetNEMA ST-20
m Core laminations of precisionsheared grain oriented silicon steelare hand stacked to insure quietoperation
• Terminations are clearly marked foreasy identification
m Three-phase transformers have one5% full capacity tap above andbelow nominal voltage for incomingsource adjustment
• Units are suitable for continuousoperation in a 40°C ambient maximum
H Full current neutrala Thermoguard protection embedded
in coils to indicate that high temper-atures (approximately 190°C) arepresent. Three-phase transformershave three thermoguards.

Please refer to Page 9-112.
Cutler-Hammer standard dry typedistribution transformers are designedfor 60 Hertz operation. Transformersrequired for other frequencies areavailable and must be specificallydesigned.
Overload Capability
Short-term overload is designed intotransformers as required by ANSI.Dry type distribution transformerswill deliver 200% nameplate load forone-half hour; 150% load for one-hour;and 125% load for four-hours withoutbeing damaged provided that a con-stant 50% load precedes and followsthe overload. See ANSI C57.96-01.250for additional limitations.
Continuous overload capacity is notdeliberately designed into a trans-former because the design objective isto be within the allowed winding tem-perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulationsystems and rise as shown below:

The design life of transformers havingdifferent insulation systems is thesame — the lower temperature systemsare designed for the same life as thehigher temperature systems.

Winding TerminationsPrimary and secondary windings areterminated in the wiring compartment.Ventilated transformers have leadsbrought out to aluminum pads that arepre-drilled to accept Cu/AI lugs. Lugs arenot supplied with these transformers.Cutler-Hammer recommends externalcables be rated 75°C for ventilateddesigns.
