Tecumseh K90-90 Overload Kit 30067439-890 Using it for higher horsepowerThe Tecumseh K90 90 Overload Kit is a critical compressor protection component engineered for high demand HVACR systems. As a primary thermal overload protector, this kit is designed to monitor the internal motor temperature and current draw, effectively breaking the electrical circuit if a locked rotor or high amperage condition occurs. This prevents catastrophic winding failure and ensures the mechanical integrity of Tecumseh compressors in
