the R5310-1530 ensures consistent linear compression across its full adjustment range

Secop Diversitech 117-7441 Potential Relay the QC-4 is identical toThe Secop Diversitech 117 7441 Potential Relay is a specialized 115V 60Hz potential relay engineered for high starting torque (HST) applications, particularly within the Secop SC series and NF model compressors. This compressor start relay utilizes a high resistance coil (terminals 2 and 5) and normally closed contacts (terminals 1 and 2) to manage the start capacitor's duration in the circuit. By sensing the Back Electromotive Force (BEMF) generated
