Arcotronics 1.27.4ACH MKP Motor Run Capacitor

The AV ARCOTRONICS 1.27.4ACH MKP motor run capacitor is a 7 µF metallized polypropylene (MKP) device designed to provide reliable phase shifting for single‑phase motors, improving starting torque and running efficiency in fans, pumps, circulators, and HVAC equipment. With a rated voltage of 420 VAC continuous (470 VAC maximum) and a 50/60 Hz rating, it combines low losses, self‑healing properties, and high ripple current capability, and it comes in a 35 mm × 56.5 mm × 63 mm package suitable for PCB or wire‑lead mounting (configuration dependent). The capacitor offers a ±5% tolerance and is designed for long service life—approximately 30,000 hours at 420 VAC (Class A) or 10,000 hours at 470 VAC (Class B)—across a -25°C to +85°C operating range. Manufactured by AV ARCOTRONICS at the Bulgaria/KEMET European Factory, this 7 µF motor run capacitor is a common replacement for industrial and commercial single‑phase motors requiring stable capacitance and continuous operation, and is suitable for maintenance and replacement tasks in equipment such as fans, pumps, circulators, and HVAC systems.
