Industrial AV C.87.8BF3-40uf Capacitor MKP AC

40 µF MKP AC motor capacitor, model C87.8BF3-40µF, is a metallized polypropylene (MKP) film capacitor designed for single‑phase AC motor circuits in industrial equipment. The 40‑microfarad value provides the phase-shift and reactive support needed by induction motors to develop torque and smooth operation in fans, pumps, conveyors, and other machinery. Constructed with an MKP dielectric, the capacitor offers high insulation resistance and self-healing properties that help tolerate voltage transients typically encountered in industrial power networks. The C87.8BF3 designation identifies its place in the C87 family and the BF3 variant, which is associated with this specific capacitance and electrical characteristics within Arcotronics’ motor-run capacitor lineup. This capacitor is intended for AC operation in motor circuits that require approximately 40 µF, and it is compatible with standard industrial AC power supplies used for single‑phase motors. When replacing capacitors for such motors, ensure the capacitance matches the motor’s requirements and that the voltage rating aligns with the system supply to maintain performance and prevent capacitor failure.
