International Environmental 70556303 Motor

The International Environmental 70556303 is a high-performance 1/15HP 115V direct drive motor engineered specifically for fan coil units (FCU) and specialized air handling applications. Operating at a nominal 1040 RPM, this 3-speed motor (60Hz, 1PH) provides the precise torque required to maintain static pressure in OEM systems like the MPY, MXY, and MUY series. As a genuine IEC replacement motor, it features an open air-over enclosure designed for optimal thermal management and longitudinal efficiency. Technicians should note the 1.30 Amp draw and the requirement for a 7.5 MFD 370V/440V run capacitor to ensure proper phase displacement and start-up torque. The 5KCP29FK6012S cross-reference confirms compatibility across multiple legacy chassis, making it a drop-in solution for restoring airflow in vertical or horizontal fan coils without needing bracket modifications. Its heavy-duty construction and ball bearing mechanism support reversible rotation (CW/CCW) to match specific blower wheel configurations found in the field.

• OEM Compatibility: Exact replacement for IEC 705563-03 and E020-70556303, ensuring proper fitment in International Environmental fan coil units.
• Multi-Speed Versatility: Integrated 3-speed leads allow for granular control of CFM delivery to meet zone-specific heating and cooling demands.
• Enhanced Reliability: Permanent Split Capacitor (PSC) design paired with direct drive coupling reduces mechanical failure points compared to belt-driven alternatives.
• Standardized Specs: Features a 1/2 inch shaft diameter and 115V single-phase electrical requirements for standard North American contractor installations.

What capacitor is required for this motor?
This motor requires a 7.5 MFD run capacitor (rated for 370V or 440V) for proper operation and to prevent winding burnout.

Can this motor replace the 5KCP29FK6012S?
Yes, the 70556303 is the authorized technical successor and direct replacement for the GE 5KCP29FK6012S model.

Is the rotation reversible in the field?
Yes, this unit is designed with reversible rotation capabilities to accommodate both clockwise and counter-clockwise blower orientations.
