ActronAir Fan Speed Capacitor P2/S2 14uF 450V is a single-phase run capacitor for outdoor fan motors requiring 14uF including 2505-134 630mm and 2505-136 710mm on ActronAir residential and commercial split ducted systems. This capacitor is rated at 14uF (+/-5%) at 450V in the 40.5x65mm 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.
