Secop Diversitech 117U6015 Start Relay

The Secop Diversitech 117U6015 Start Relay is a critical OEM electrical component engineered for High Starting Torque (HST) applications within demanding commercial refrigeration environments. This current-type potential relay is vital for managing the compressor start winding, ensuring efficient motor ignition by handling pickup current up to 4.40 A and a nominal dropout current of 3.55 A (minimum 3.20 A). Field technicians typically specify this relay for Danfoss/Secop FR-Series and SC-Series hermetic compressors, where reliable torque is necessary to overcome high differential pressures at startup.

Designed for systems utilizing R134a refrigerant, the 117U6015 provides a precise electrical break to prevent winding overheat and potential motor failure. Its robust construction is optimized for heavy-duty appliances including reach-in coolers, ice cream freezers, and commercial beverage dispensers. When troubleshooting compressor starting issues or replacing a pitted or failed refrigeration start relay, utilizing this genuine Secop component ensures exact electrical matching to factory specifications, maintaining the high-performance standards of the original equipment manufacturer.

Key Benefits for Technicians

• Optimized HST Performance: Provides the necessary current surge for Secop HST compressors to start under loaded conditions.
• Precise Electrical Tolerances: Features a calibrated 3.55 A dropout current to accurately disengage the start capacitor after motor synchronization.
• Broad Compatibility: Seamlessly integrates with FR series compressors and various commercial 115V-230V refrigeration platforms.
• Simplified Installation: Standard spade terminal configuration enables rapid field replacement, reducing downtime for commercial clients.
• Application Versatility: Suitable for a wide range of evaporation temperatures in both low-back-pressure (LBP) and high-back-pressure (HBP) systems.

Common Questions

Is the 117U6015 compatible with LST (Low Starting Torque) compressors?
No, this relay is specifically calibrated for High Starting Torque (HST) motors. Using an HST relay on an LST system or vice-versa can lead to improper winding engagement and winding damage.

What are the signs of a failing 117U6015 start relay?
Common indicators include the compressor "humming" but failing to start, the thermal overload protector tripping frequently, or visible heat damage on the relay casing terminals.

Can I use this relay with R290 or R600a systems?
While functionally similar, you must verify the specific compressor data sheet. This model is primarily optimized and documented for R134a commercial refrigeration applications.
