Danfoss 117U5017 Start Capacitor

The Danfoss 117U5017 Start Capacitor is a critical electrical component designed specifically for SC model compressors, providing the necessary torque for reliable compressor startup in high-back-pressure and commercial refrigeration applications. Rated at 80 microfarad and 220V, this round start capacitor ensures the motor can overcome initial inertia and high head pressures without overheating the windings. Built to original equipment manufacturer (OEM) specifications, it maintains strict capacitance tolerances and high insulation resistance to prevent premature failure during frequent cycling. When performing a HVAC capacitor replacement, this unit is the standard choice for Danfoss SC10, SC12, and SC15 Series compressors using 220-240V 50/60Hz power supplies. Proper installation involves ensuring the bleeder resistor (if applicable) is intact to prevent arcing and ensuring the terminal connections are secure to avoid high-resistance heat build-up. Using this 80 uF 220V capacitor guarantees the starting torque required for heavy-duty refrigeration compressor parts maintenance and repairs.

• Optimized Starting Torque: Provides the specific 80 microfarad capacitance needed to move Danfoss SC compressors out of a locked-rotor state.
• High-Voltage Stability: Rated for 220V operation to handle voltage fluctuations common in commercial environments.
• Precision Fitment: Standardized round housing fits original Danfoss starting relay covers and mounting brackets without modification.
• Enhanced Thermal Durability: Constructed to withstand the high temperatures found in compact refrigeration condenser housings.

What compressors are compatible with the Danfoss 117U5017?
This component is secondary-matched specifically for Danfoss SC Series compressors requiring an 80 microfarad start assist. It is commonly found in refrigeration units utilizing SC10G, SC12G, and SC15G hermetic compressors.

Can this capacitor be used on 110V systems?
No, this unit is rated for 220V. Using a capacitor with a voltage rating lower than the system’s peak voltage will lead to dielectric breakdown and immediate component failure.

Does this unit come with a bleeder resistor?
Technicians should verify the specific compressor wiring diagram; while many Danfoss start capacitors interface with a starting relay that handles discharge, always check for the presence of a resistor if required by the local electrical code.
