Danfoss 117U6102 Relay How do I know ifThe 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
