Tecumseh K71-19 Relay Kit

As a field technician, you know that a soft start isn't just a preference—it's a requirement for system longevity. The Tecumseh K71-19 Relay Kit is the professional-grade solution for managing compressor start-up and operational cycling in demanding refrigeration and air conditioning environments. Engineered specifically for AEA5460EXA-1 compressor models and related high-capacity hermetic units, this kit provides a high-amperage switching capacity rated at 35A 400VAC to handle the heavy inrush current typical of industrial inductive loads.

Replacing an obsolete 820ARR3C32 or 820ARR3A46 with the K71-19 ensures precise electrical timing during the start-up phase, preventing motor winding overheating and reducing the risk of terminal venting. This OEM Tecumseh replacement part integrates seamlessly into existing control circuits, providing critical power control and overload mitigation. Whether you are performing a field repair or a planned system overhaul, using this HVAC startup relay kit maintains the factory-specified performance standards required for high-pressure refrigeration applications.

• Direct Compatibility: Engineered as the standard field replacement relay for Tecumseh AEA5460EXA-1 and similar single-phase compressor configurations.
• Industrial Build Quality: Robust internal components designed to withstand the rapid cycling and thermal stresses of commercial refrigeration.
• Protective Performance: Enhances compressor motor protection by stabilizing the starting torque and ensuring a clean break on the contacts.
• UL Recognized: Validated for safety and electrical integrity in high-voltage HVACR applications.

• Can I use this kit to replace a different brand's potential relay? It is highly recommended to stick to the cross-reference guide; this kit is designed for specific Tecumseh compressor units to ensure the coil and contact ratings match the motor characteristics.
• Is this suitable for 208-230V systems? Yes, with a 400VAC rating, it comfortably handles standard commercial voltage phases used in refrigeration relay kits.
• Does it include the mounting strap? Compatibility with standard bale straps or bolt-down configurations is standard for the K71-19 footprint.
