Motors and Armatures 11050 Start Capacitor 161-193 Mfd 250V

Product Description

The MOTORS AND ARMATURES 11050 is a start capacitor rated at 161-193 microfarads (MFD) and 250 volts, designed to provide the momentary starting torque needed to bring single-phase compressor and motor windings up to operating speed. Start capacitors are used in series with the start winding circuit and are switched out of the circuit once the motor reaches a set threshold speed. This component is a standard replacement part installed by HVAC technicians servicing residential and light commercial refrigeration and air conditioning equipment.

This start capacitor is suited for single-phase motor applications where additional starting torque is required. Typical installations include condensing unit compressors and fan motors in residential split systems, package units, and room air conditioners. The 161-193 MFD range accommodates motor applications that require a capacitance tolerance window rather than a fixed value, and the 250-volt rating is appropriate for standard 115-volt and 208/230-volt single-phase circuits where starting duty is intermittent.

Key Features

• 161-193 MFD capacitance range provides flexibility across compatible single-phase motor starting applications
• 250-volt rating suitable for 115V and 208/230V single-phase HVAC and refrigeration circuits
• Intermittent-duty design engineered for the brief, high-current demand of motor starting cycles
• Direct replacement form factor for standard round start capacitor applications

Compatibility

Designed as an OEM-style replacement start capacitor for single-phase compressors and motors in residential and light commercial HVAC and refrigeration systems requiring a 161-193 MFD, 250-volt start capacitor.

Installation Notes

Start capacitors are serviced by licensed HVAC technicians. Disconnect and lock out all power to the unit before handling any capacitor — capacitors store a charge and must be safely discharged before removal. Follow NEC guidelines for equipment grounding and conductor sizing. Never substitute a run capacitor for a start capacitor, as they are not interchangeable by design or duty cycle.
