35MFD 370V ROUND RUN CAPACITOR
Product Overview
What pool techs reach for when single-phase pump motors hum, overheat, or fail to start under load.
The Super-Pro 35 MFD 370V round run capacitor (part number 12718 by JARD/MARS) delivers standard-spec electrical phase-shift performance for single-phase pool pump motors. Built with cURus and CE safety ratings, this round-cased unit provides stable continuous capacitance to keep motor windings operating efficiently in high-heat equipment pad environments.

Benefits & What Makes It Different
35 MFD / 370 VAC Specification
Delivers the precise capacitance and voltage rating required by compatible pool and spa pump motors.
JARD by MARS Reliability (12718)
Manufactured to rigorous cURus and CE standards for reliable heat dissipation and long service life.
Round Form Factor
Engineered to fit standard round motor capacitor covers and rear end-bells without clearance issues.
Compatibility
- Single-phase pool and spa pump motors requiring a 35 MFD (µF) 370V round run capacitor
- Direct replacement for JARD by MARS item # 12718
- Cross-compatible with Century, AO Smith, and US Motors units matching 35 µF 370VAC specs
When To Use This
Pro Tip
Direct sunlight and ambient heat degrade dielectric oil inside capacitors faster than runtime alone. If your equipment pad gets intense afternoon sun, check actual capacitance with a multimeter annually to catch degradation before your motor overheats.
Common Questions & Instructions
What symptoms indicate my pool pump capacitor has failed?
A failing run capacitor typically causes the pump motor to emit a loud hum without spinning, trip the breaker at startup, overheat quickly, or show visible bulging and fluid leaking from the top terminal seal.
Can I install this 35 MFD 370V run capacitor myself?
Yes, installation is relatively straightforward, but safety is critical. You must disconnect breaker power and discharge stored energy across the terminals using an insulated screwdriver before handling the wiring.
Can I replace a 370V capacitor with a 440V rated capacitor?
Yes, you can safely use a higher voltage rating such as 440V in place of 370V, but you must always match the exact 35 MFD capacitance required by your motor nameplate.
