Danfoss Compressor Start Relay | 117-7029

Product Description: The 117-7029 is a critical electrical component used to facilitate the starting torque of compressor motors. In the high-ambient heat of Dubai and the Northern Emirates, compressors are under constant pressure to cycle efficiently; this relay ensures that the start winding is energized only long enough to bring the motor up to speed. By providing a clean and precise electrical disconnect, it prevents the start winding from burning out, which is a common cause of compressor failure in the Middle East. It is a standard replacement part for technicians servicing water coolers, domestic fridges, and small commercial displays throughout the UAE.

Key Features & Benefits:

• Optimized Starting: Delivers the necessary electrical impulse to start the compressor reliably, even during the peak voltage fluctuations common in some UAE industrial zones.
• Winding Protection: Safely disconnects the start winding to prevent overheating and premature motor failure.
• Climate Resilience: Manufactured to maintain consistent electrical performance in the high-humidity and high-temperature environments of the UAE coast.
• Genuine Danfoss Quality: Ensures perfect electrical compatibility with Danfoss reciprocating compressors, reducing the risk of intermittent start failures.
• Plug-and-Play Installation: Designed for a secure, direct fit onto compressor terminal pins, making it a favorite for UAE service contractors for rapid on-site repairs.

FAQs:

• Q: How do I know if my 117-7029 relay is failing?
• A: If you hear the compressor trying to start with a “click” but it stops immediately, or if the unit is humming without starting, the relay is likely faulty and should be replaced.
• Q: Can I use this relay for 60Hz systems in the UAE?
• A: This model is typically optimized for 50Hz (UAE standard). Always check the specific frequency rating on the relay body to ensure it matches your equipment.
• Q: Is it safe to replace this relay myself in Dubai?
• A: Because it involves high-voltage electrical connections, it is strongly recommended that a qualified UAE HVAC technician performs the replacement to ensure safety and proper grounding.
