300uF/450V Motor Starting Capacitor for Electric Motors
This starting capacitor ensures the efficient start of electric motors in household and industrial appliances. The 300 microfarad capacity and 450V working voltage guarantee safe operation in compressors, pumps, fans, and single-phase motor equipment. The professional solution for quick replacement of faulty capacitors.
What you get with this product
- Instantly restart faulty motors — compatible with AC compressors, water pumps, industrial fans, and household appliances
- Quick installation with 4 male spade terminals and included mounting screw — replace the worn capacitor in under 10 minutes
- Stable operation between -40°C and +85°C — withstands extreme conditions in cold rooms or industrial spaces
- Only 5% tolerance ensures the exact starting current needed by the motor — eliminates overloads and extends lifespan
- UL 94 V-2 flame-retardant plastic casing — maximum protection against overheating and fire risk
- Self-healing polypropylene dielectric significantly extends lifespan compared to conventional capacitors
How it works and how to install
The capacitor supplies the necessary starting current to the single-phase electric motor, creating the magnetic phase shift that initiates rotation. When the current is off, secure the capacitor to the metal support using the included screw and nut, then connect the male terminals according to the appliance's electrical diagram. 2000V insulation between terminals and casing guarantees installation safety.
Frequently asked questions
How do I know the old capacitor is faulty?
The motor makes a humming noise but doesn't start, or the capacitor casing is swollen and shows oil leaks. In both cases, immediate replacement is necessary.
Can I use this capacitor with any single-phase motor?
Yes, if the motor requires 300uF and operates at a maximum voltage of 450V AC. Check the specifications on the motor's nameplate before installation.
How long does a starting capacitor last before failing?
At 450V, the nominal lifespan is 3000 hours of effective operation. Usage at lower voltages significantly extends its lifespan.
