Tecumseh K90-38 Relay Kit
Ensure the longevity and electrical integrity of your refrigeration systems with the Tecumseh K90-38 Relay Kit. Designed as a direct-fit compressor overload protector, this essential thermal management component monitors current draw to prevent catastrophic motor failure caused by overheating or electrical surges. As a veteran-grade HVAC replacement part, the K90-38 is engineered for commercial and residential Tecumseh refrigeration compressors, providing a critical failsafe that interrupts power during unsafe operating conditions. The integrated automatic reset overload functionality allows the motor to cool to safe parameters before re-engaging, minimizing system downtime and preventing unnecessary service calls. Whether you are performing a routine swap or troubleshooting a stalled compressor, this OEM-spec relay kit delivers the precise trip-time sensitivity required to protect internal windings from excessive amperage. This kit is a staple for contractors maintaining energy-efficient cooling setups where reliable motor starting and thermal protection are non-negotiable for system uptime.
Key Benefits- Precision Thermal Protection: Effectively shields compressor motors from heat-induced damage during locked rotor conditions or high-ambient operation.
- OEM-Level Compatibility: Specifically calibrated for Tecumseh compressor motors, ensuring correct trip curves and electrical resistance.
- Automatic Reset Logic: Reduces manual intervention by automatically restoring power once temperatures return to a safe operating range.
- Enhanced System Reliability: Optimized to handle inrush current during startup while maintaining sensitivity to continuous overcurrent faults.
Is the K90-38 compatible with residential air conditioning units?
Yes, this overload relay is utilized in various residential and light commercial HVAC applications that feature Tecumseh-branded compressors. Always verify the compressor’s model and electrical data for exact matching.
What is the primary difference between this relay and a standard circuit breaker?
While a circuit breaker protects the entire circuit from short circuits, this compressor relay kit is thermal-sensitive and specifically protects the motor from drawing too much current over a sustained period.
Does this kit include everything needed for a standard field replacement?
The K90-38 is a complete kit designed to replace the existing overload component on the compressor terminal assembly, ensuring a secure and conductive connection for reliable performance.
