Marvair 40046 Round Start Capacitor Overview
The Marvair 40046 is a heavy-duty round start capacitor engineered to deliver the high-torque starting boost that HVAC motors demand. With a capacitance range of 270–324 microfarads (µF) and a rated voltage of 165VAC, this capacitor is purpose-built to energize compressor and motor windings during startup, then disengage once the motor reaches operating speed.
Key Specifications

Features & Benefits
- Wide capacitance tolerance (270–324 µF) ensures compatibility across a range of motor starting requirements
- 165VAC rating designed for single-phase motor start circuits commonly found in HVAC equipment
- Round housing for easy installation in standard capacitor brackets and mounting clips
- Genuine Marvair OEM replacement part for reliable, like-for-like performance
- Provides the surge of starting energy needed to bring compressors and fan motors up to speed quickly
Application
The Marvair 40046 start capacitor is a direct OEM replacement designed for use in Marvair HVAC systems. Start capacitors are used in single-phase induction motors to increase the starting torque. Once the motor reaches a sufficient speed, the start capacitor is switched out of the circuit by a start relay or potential relay. This capacitor is ideal for technicians servicing Marvair packaged terminal air conditioners (PTACs), commercial HVAC units, and other compatible equipment requiring a 270–324 µF, 165VAC round start capacitor.
