Secop Diversitech 117U4129 Starting Relay

The Secop Diversitech 117U4129 Starting Relay is a specialized electromechanical component designed for high-performance 115V refrigeration compressor applications. Built for the rigors of commercial and residential cooling systems, this 1/4" connection starting relay is essential for initiating the start winding of compatible compressors, specifically optimized for the Secop NF7CLX-1 series. By momentary connecting the start winding and disconnecting once the compressor motor reaches operating speed, it ensures smooth torque delivery and efficient power cycles. The integrated Klixon thermal protector provides a critical layer of system security, monitoring internal temperatures to prevent winding burnout during voltage spikes or locked-rotor conditions. This OEM Secop replacement part maintains precise electrical timing to reduce stress on the HVAC compressor, ensuring consistent startup even in high-ambient environments or demanding duty cycles.

• Optimized Compressor Performance: Specifically engineered as a compressor starting relay to provide the necessary torque for 115V, 60Hz systems.
• Integrated Thermal Safety: Features a built-in Klixon protector that automatically resets, preventing permanent damage from overcurrent or overheating.
• Precision Fit: Standard 1/4" spade terminal design allows for rapid field replacement in commercial refrigeration units.
• Genuine OEM Quality: A direct replacement for 117U4129, ensuring electrical values match factory specifications for long-term system stability.
• Broad Compatibility: Primarily utilized with Secop/Danfoss compressors like the NF7CLX-1 for 1/3 HP applications.

Is the 117U4129 compatible with variable-speed compressors?
No, this relay is designed for standard single-speed 115V induction motors. Always verify your compressor model number before installation.

What are the symptoms of a failing starting relay?
Technicians typically look for compressor "short cycling," humming without starting, or the Klixon protector tripping repeatedly due to a failed internal contact point.

Can I use this relay with an external start capacitor?
While this unit provides the essential starting pulse, the circuit configuration must match the manufacturer’s original wiring diagram for the specific compressor model.
