Danfoss 117U6102 Relay

The Danfoss 117U6102 relay is a critical electrical component designed for Danfoss SC compressors, specifically engineered to manage start capacitor engagement in refrigeration systems. This potential relay acts as a sensing device that monitors the voltage across the start winding, ensuring the start-up torque is sufficient for high back pressure (HBP) and low back pressure (LBP) applications. Built for hermetic compressor reliability, the 117U6102 provides precise switching cycles to prevent motor burnout. For field technicians and contractors, verifying the microfarad rating and AC voltage compatibility is essential when replacing Danfoss electrical starting equipment. This specific 117U relay series is optimized for HVACR commercial units, maintaining consistent motor control under heavy electrical loads. By integrating this OEM Danfoss compressor part, you ensure that the compressor's electrical circuit adheres to original manufacturer specifications, protecting the starting torque integrity and overall system efficiency.

• System Compatibility: Engineered specifically for Danfoss SC-series hermetic compressors to ensure seamless electrical integration.
• Starting Performance: Provides reliable management of start capacitors, optimizing the compressor motor start-up phase.
• Industrial Durability: Constructed to endure high-cycle switching without early contact fatigue or degradation.
• OEM Standards: Matches exact electrical tolerances required to maintain the hermetic refrigeration cycle.

Common Questions

How do I confirm if the 117U6102 is the correct relay for my SC compressor?
Reference the compressor’s data sheet or the electrical diagram on the terminal cover. The Danfoss 117U series is specific to the motor type and capacitor configuration of the SC frame.

Will this relay work with non-Danfoss start capacitors?
While technically possible if specifications match, it is recommended to pair this with OEM Danfoss capacitors to ensure the dropout voltage parameters and MFD requirements are fully synchronized.

What causes a Danfoss potential relay to fail prematurely?
The most common causes are voltage fluctuations, improper capacitor sizing, or excessive short-cycling of the compressor, which leads to contact pitting.
