50 / 63uF Variable Hot Tub Capacitor
This is a cheaper version of the expensive American 53 / 64 capacitor used on most smooth sided Aqua-Flo pumps 48 Frame (XP2 and XP2E).
Note the capacitor still covers the uF range, but is physically larger in size.
Mount size 10cm x 2.8cm
Capacitor without cap size 8.4cm x 4.7cm
2 x 2 Spade connectors
The capacitor does however come with a mounting bracket to enable external mounting.
Do not attempt to change a hot tub capacitor if the pump is still plugged in or the tub is still switched on. Capacitors generate very high voltage which can be dangerous.
The simplest way to explain the mechanics of a hot tub capacitor would be to compare it to a battery. Both store and release electricity. Capacitors are charged with electricity, then releases its stored energy at a rate of sixty times per second in a 60 cycle alternating current system. The sizing is critical to motor efficiency just as sizing of batteries is critical to a radio. A radio that requires a 9V battery will not work with a 1.5V size battery. Thus, as the battery becomes weaker the radio will not play properly. A motor that requires a 7.5 mfd hot tub capacitor will not work with a 4.0 mfd capacitor. Much the same way, a motor will not run properly with a weak capacitor. This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings. Motor manufacturers spend many hours testing motor and capacitor combinations to arrive at the most efficient combination.
