The Bussmann LP-CC-20 Class CC time-delay fuse is a compact overcurrent protection device designed for HVAC electrical circuits, including control panels, air conditioners, and furnace systems. It operates by allowing temporary inrush currents while interrupting sustained overloads or short circuits to protect sensitive components. Commonly used in compressors, fan motors, and control transformers, it enhances system reliability and safety. Its time-delay feature prevents nuisance interruptions, supports consistent performance, and helps extend equipment lifespan by minimizing electrical damage and downtime.
