Tecumseh K71-64 Start Relay

The Tecumseh K71-64 Start Relay is a specialized electromechanical component engineered for precise compressor motor initiation in refrigeration and air conditioning systems. Designed for high-performance single-phase applications, this potential start relay operates on a 208-230V, 60 Hz electrical circuit, facilitating the critical transition between start and run cycles. It serves as an essential direct replacement for the 820ARR3J44 starting device and is commonly integrated with the AWG5515EXN series and other high-capacity reciprocal compressors. By providing consistent electrical contact for the start winding, the K71-64 ensures reliable torque management during heavy-load startups.

For field installations, this OEM Tecumseh start relay features standard spade terminal configurations, allowing for a streamlined retrofit or upgrade of existing control circuits. Technical specifications confirm compatibility with K146-44 start capacitors and K150-06 run capacitors, making it a staple for contractors servicing commercial coolers and industrial HVAC units. The robust internal mechanism is built to withstand the thermal demands of rapid cycling, assisting in the prevention of motor burnout and maintaining the operational efficiency of the entire refrigeration loop.

• Precise Direct Replacement: Engineered specifically to replace part number 820ARR3J44 for zero-hassle mechanical fitment.
• High-Voltage Stability: Rated for 208-230V / 1Ph / 60Hz systems to meet rigorous commercial electrical standards.
• Optimized Motor Starting: Provides necessary torque Boost for CSIR and CSR motor configurations under high head pressure.
• Integrated Cross-Compatibility: Validated for use with K146-44 and K150-06 capacitor sets and AWG5515EXN compressors.

Is the K71-64 a direct replacement for the 820ARR3J44 potential relay?
Yes, the K71-64 is the factory-designated replacement for the 820ARR3J44 and maintains the same mounting footprint and electrical characteristics.

What voltage systems is this start relay compatible with?
This component is designed specifically for 208V to 230V single-phase systems. It should not be used in 115V applications.

Can I use this relay with an AWG5515EXN compressor?
Yes, this relay is the standard technical requirement for the AWG family of reciprocal compressors, ensuring proper timing of the start winding disconnect.
