Arcotronics 1.27.4ACH MKP Motor Run Capacitor

Description:

The AV ARCOTRONICS 1.27.4ACH MKP Capacitor is a metallized polypropylene (MKP) motor run capacitor used in single-phase electric motors to improve starting torque and running efficiency. Commonly installed in fans, pumps, circulators, HVAC equipment, and low-power electric motors where reliable phase shifting and continuous-duty operation are required. Maintenance teams and motor repair technicians use this capacitor for equipment repairs, preventive maintenance, and replacement of failed motor capacitors. The capacitor is rated at 7 µF and designed for long service life at voltages up to 470 VAC.

Applications:

The AV ARCOTRONICS 1.27.4ACH MKP capacitor is widely used in industrial and commercial equipment requiring continuous motor operation and stable capacitance values. It is commonly found in air fans, water pumps, circulators, HVAC systems, and other single-phase motors where improved starting characteristics and efficient operation are critical. The metallized polypropylene construction provides self-healing properties, low losses, and high reliability in demanding environments.
