Danfoss 117U6012 Starting Relay

The Danfoss 117U6012 Starting Relay is a high-reliability compressor start component designed for fractional horsepower hermetic compressors. Engineered specifically for use with HST (High Starting Torque) systems, this potential relay ensures stable motor initiation by managing the start capacitor circuit during the critical startup phase. This 117U6012 relay is compatible with Danfoss FR and SC series compressors, providing the precise voltage-sensitive switching required to protect the start windings from overheating. For contractors servicing commercial refrigeration equipment, this part is a standard drop-in solution for maintaining factory specifications in R134a and R404A systems. Its robust design handles high-frequency cycling, making it a dependable choice for reach-in coolers and ice machines that demand consistent torque under varying load conditions. Integrating this Danfoss compressor relay prevents common mechanical failures associated with generic alternatives, ensuring long-term efficiency and motor protection in LBP/MBP applications.

• Precise Voltage Sensing: Optimized for Danfoss compressor starting to ensure 115V motor coils engage and disengage at the correct EMF thresholds.
• High Torque Support: Essential for systems utilizing expansion valves (TXV) where high starting torque is required to overcome pressure differentials.
• Durable Contact Points: Built to withstand the high-inrush current typical of refrigeration compressor startup cycles.
• OEM Compatibility: Guaranteed fit for FR8.5G, FR10G, and SC12G Danfoss models, eliminating field-fit guesswork for technicians.

Common Questions:

Is the Danfoss 117U6012 compatible with any 115V compressor?
No, this relay is specifically calibrated for Danfoss hermetic compressors. Always verify your compressor model number against the 117U6012 technical specifications to ensure the trip-out and pick-up voltages align with the motor's winding requirements.

Does this relay require a specific start capacitor?
Yes, for HST (High Starting Torque) configurations, this relay must be paired with the manufacturer-recommended microfarad (µF) rated capacitor to ensure sufficient torque without damaging the start winding.

What causes a starting relay like the 117U6012 to fail?
The most common causes are low line voltage, which prevents the relay from reaching the pick-up voltage, or a failing compressor motor pulling excessive amperage, which leads to pitted or welded contact points.
