Danfoss 8173022 Relay
The Danfoss 8173022 Start Relay is a mission-critical electrical component designed for high-torque motor starting in commercial refrigeration and HVAC systems. Engineered for reliability in fractional horsepower compressors, this potential-style relay ensures precise disconnection of the start capacitor once the motor reaches sufficient speed, protecting the windings from overheating. This specific Danfoss compressor relay is built to withstand the rigorous cycling demands of R134a, R404A, and R290 systems, making it a standard replacement for OEM Danfoss electrical parts. It features 1/4-inch spade terminals for secure, low-resistance connections, minimizing voltage drop during high Locked Rotor Amp (LRA) events. For technicians managing walk-in cooler repairs or reach-in freezer maintenance, maintaining an inventory of this start relay replacement is essential for minimizing equipment downtime. Its robust internal contact design prevents pitting and arcing, ensuring consistent performance across various voltage and frequency ranges typical of North American electrical grids.
Key Benefits for Technicians:- High-Torque Performance: Provides the necessary electrical kick for compressors to overcome high head pressures during hard start conditions.
- Precise Cut-Out: Accurate sensing of back-EMF ensures the start circuit is disengaged at the optimal moment, preventing winding damage.
- Durable Construction: Built with high-grade materials to resist the heat and vibration common in condensing unit housings.
- Simplified Installation: Standardized terminal layout allows for quick wiring harness integration, reducing billable labor time.
- Can I use this relay on other compressor brands? This relay is specifically calibrated for Danfoss-approved motor profiles; checking the compressor cross-reference guide is mandatory for proper electromagnetic matching.
- What causes this relay to fail prematurely? Frequent short-cycling or improper start capacitor sizing can lead to contact welding or coil burnout.
- Does this relay include the start capacitor? This is the Danfoss 8173022 relay only; the capacitor must be sourced separately based on the specific motor requirements.
