Supco cs124-156x220 Start Capacitor 124-156 Mfd 220VAC

Product Description

The SUPCO cs124-156x220 is a round start capacitor rated for 124 to 156 microfarads (MFD) at 220 volts AC. Start capacitors provide the extra torque needed to bring a motor up to operating speed, then drop out of the circuit once the motor is running. This part is sized for single-phase PSC and capacitor-start motor applications common in residential and light commercial HVAC compressors and fan motors. Licensed HVAC technicians are the primary installers. The operating temperature range of -40 degrees F to 149 degrees F suits a wide range of installation environments, and UL and VDE listings confirm compliance with recognized safety standards.

This start capacitor is suited for single-phase motor applications in residential and light commercial systems where the existing capacitor falls within the 124 to 156 MFD range at 220 volts AC. Typical applications include air conditioning compressor motors and condenser fan motors that require a start-duty capacitor. When replacing a failed or degraded capacitor, verify the MFD rating and voltage rating of the original unit before installing this part.

Key Features

• Capacitance range of 124 to 156 MFD covers common start-duty motor requirements
• Rated at 220 volts AC for compatibility with standard single-phase motor circuits
• Operating temperature range of -40 degrees F to 149 degrees F for broad climate suitability
• UL and VDE listed for recognized safety compliance
• Round case measuring 1-13/16 inches diameter by 3-3/8 inches height

Compatibility

Designed as an OEM-style replacement start capacitor for single-phase motors requiring a 124 to 156 MFD rating at 220 volts AC. Confirm the MFD range and voltage rating of the original capacitor before substituting this part.

Installation Notes

Start capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out power to the unit before beginning any capacitor service. Capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely using an approved resistive discharge tool before handling. Follow applicable NEC guidelines for low-voltage wiring and motor circuit connections.
