RESCUE K55HXJZH-2375 Furnace Blower Motor – 3/4 HP, 115V, 1075 RPM, 4-Speed, CCW Rotation, 48Y Frame – US Motors 5470 Replacement

Condition: New – No visible defects or missing components. Ready for immediate installation.

The US Motors K55HXJZH-2375 is a high-efficiency, multi-speed RESCUE® replacement blower motor, engineered for use in residential HVAC systems. Designed to replace a broad range of OEM motors, this model offers universal mounting options, a durable build, and energy-saving performance. It is commonly used in furnaces, air handlers, and other forced air systems requiring a 4-speed, 1075 RPM motor with continuous duty rating.

Built with a 1/2″ x 5.0″ shaft, the K55HXJZH-2375 supports both bracket and belly band mounting and features a capacitor-not-included design, so an external 10 µF capacitor is required. With versatile horsepower taps ranging from 1/5 to 3/4 HP and 115V single-phase operation, this motor is ideal for service technicians looking for a reliable, field-proven universal motor.

Capacitor Pairing for US Motors K55HXJZH-2375 RESCUE Blower Motor

The US Motors K55HXJZH-2375 requires a run capacitor, not included with the motor. Proper capacitor matching is critical for motor efficiency, starting torque, and overall reliability.

Recommended Capacitor Specs:

• Capacitance: 10 µF (microfarads)
• Voltage Rating: 370V AC (minimum)
  For added durability and future-proofing, you can use a 440V-rated capacitor instead. It is fully compatible and provides extra voltage tolerance in high-heat applications.
• Type: Oval or round run capacitor, non-polarized
• Terminals: Usually 2-terminal or 4-terminal with quick-connect tabs

Wiring Note:

This motor is PSC (Permanent Split Capacitor) type:

• Capacitor connects between the two brown wires labeled “BR” or “BRN”
• If one brown wire has a white stripe (BRN/WH), that may be connected directly to line power (L1) depending on the specific wiring diagram provided with the motor
• Always verify wiring with the diagram on the motor label or factory manual

Recommended Capacitor Models:

These are typical compatible models:

• MARS 12290 (10 µF, 370V, oval)
• Packard PRC10 (10 µF, 370V/440V, round)
• Titan HD TRCF10 (10 µF, 440V, round)
• GE Industrial 97F9002 (10 µF, 370V, oval)

Tips for Selection:

• Match the µF exactly (10 µF)
• Voltage can be equal or higher (370V or 440V is fine)
• Use oval style if the motor bracket area is tight
• Always use motor-rated capacitors; avoid low-cost unbranded ones, which can fail prematurely
