HEAVY DUTY SERIES ROTO-PHASE II
Standard Features:
- Specify 230 VAC or 460 VAC
- ODP or TEFC Design Units Available
- Continuous Operating Duty Cycle
- 1-YEAR WARRANTY
The Heavy Duty Roto-Phase is designed to start ONE “hard starting” motor based on the rotary phase converter’s Largest Motor HP rating plus miscellaneous smaller motor loads equal to or less than the Maximum Recommended HP Capacity. It can also handle a start-up load of TWO motors of the same HP rating as the Largest Motor rating of the phase converter if they are sequentially started and operated under light loads. This unit has a greater capacity than any rotary phase converter made. The reason for the larger horsepower capacity of this unit is due to the increase in physical size. The heavy duty converters are substantially larger in comparison than our competitor’s units which are listed at a heavy duty rating. This allows the converter the capability of starting motors that are “hard starting” or operating more three phase motor load. The Heavy Duty Series Design is capable of handling the tough jobs such as: CENTRIFUGAL WATER PUMPS, GRAIN DRYERS, FERTILIZER MIXERS, DOUGH MIXERS, REFRIGERATION COMPRESSORS, AIR COMPRESSORS, and RESISTIVE LOADS as well as multiple inductive motor loads. The largest motor horsepower rating is in true horsepower and is not intended to operate mis-rated motors or motor loads. Where TWO motors match the Largest Motor Rating of the phase converter and are “simultaneously” started, then you would need to choose the Roto-Phase Converter model which matches the TOTAL horsepower of the two three- phase motors. When using this series of converter with “high efficiency” motor loads, please consult factory.

NOTE: When ordering the phase converter with the magnetic starter control package, you will need to add the Prefix Letter “C” (Automatic unit with starter, OL protection, and time-delay relay), or Prefix Letter “C/” ( Manual unit with starter, OL protection, and push button START/STOP station).
With the addition of optional features, the panel size of the phase converter model may change – Please Consult Factory.
