MARS - Motors & Armatures 11952 Round OEM Mars2 Start Capacitor

I purchased this to replace my 10” Rockwell Unisaw’s capacitor. Motor was just humming and not spinning. Checked the voltage at the low voltage box. Everything checked good. Removed the motor and smelled it. Nothing burned. Removed and tested the capacitor. Read 0 (zero). Was a little apprehensive to just replace but what else could it be..... So, replaced it and all is good. Saw is working. Only item noted was the physical size. Much smaller than what I removed. Hoping the duty cycle is equal to what I removed!

Replaced a bad start capacitor in my dehumidifier. The old one was a 200-240 uF 250V. This new one rated 216-259 uF tested at 235 uF and the dehumidifier is now working again. The compressor would just hum when turned on pointing to the start capacitor as the most likely problem. Sure enough.

Perfect match

Smaller in size than other brands.

This replaced the start capacitor on a `1HP 110 single phase tablesaw and it made it work again. This capacitor is larger than the original so I tucked it into a 6" length of 2" pvc pipe to cover the contacts on the end... not osha approved but good enough for me. With capacitors you don't have to get all caught up on the exact capacitance, but keeping the max voltage rating high is good practice.

Performed well, would buy again

One day the the motor failed to stat and would just pop the breaker, quick inspection found the terminals broke off the original capacitors. The specs on these matched, ordered a pair and put them on 2 days later. Now it's working great again. It was on a 7.5HP 230V Baldor motor.

happy

I used this for an electric motor on my compressor - worked perfect!

Unfortunately for me,I smoked this unit immediately because I didn't check to see if the centrifuge doomahicky inside the motor didn't disengage once the motor started spinning so the juice just keeps feeding the unit electricity. So everyone, just need to check if the contacts will release. Don't assume

Turns out, this was not needed. Tested it for future use anyway. Tested just as it should. Good quality ... good price.

Great value for the money. Works better than the OEM one.

I wish I took a picture it is a hell lot smaller than the original but I just wrap some cardboard around it with some tape and stuck it back in there so it doesn't rattle around its been in there running my compressor for about a year now At runs every Saturday and Sunday that I work in the shop that's all lot of work
