ActronAir Fan Speed Capacitor P2/S2 6uF 450V is a single-phase run capacitor for outdoor fan motors requiring 6uF on ActronAir residential and commercial split ducted systems. This capacitor is rated at 6uF (+/-5%) at 450V in the 30x60mm M8 Stud format -- a degraded run capacitor is the most common cause of AC fan motor failure, causing the motor to run on the start winding and overheat before burning out. Always replace the run capacitor whenever an AC fan motor is replaced. Isolate power at mains before replacing any capacitor components.
