The CARRIER KAACH1901AAA crankcase heater is designed to warm the compressor crankcase during the off cycle, operating at 480V. It is wired across the open contacts of the contactor, activating when the contactor is de-energized. This heater warms the oil, reducing refrigerant migration and ensuring proper compressor lubrication. It is essential for low ambient applications utilizing a MotorMaster, specifically for 24ABB3 models (Sizes 042 to 060).
