Nidec-Secop 117U6003 Start Relay

The Nidec-Secop 117U6003 Start Relay is a component used to start the compressor by connecting the start winding. It senses voltage variations and alternates the start winding in & out of the circuit as the compressor starts and aids in the correct torque building up of the motor. It is installed in the electrical compartment which is close to the compressor and is linked to the control and power wiring to synchronize timing with the contactor. This relay is useful to enhance compressors and secure constant cooling and heating efficiency in air conditioners, heat pumps and refrigerated HVAC systems.
