Carrier JKS-80 80-Amp Class J Cartridge Fuse

The Carrier JKS-80 is an 80-Amp Class J time-delay cartridge fuse designed for use in Carrier HVAC and refrigeration equipment. This fuse provides reliable overcurrent protection for compressors, motors, and control circuits, helping to safeguard equipment from damaging electrical surges and short-circuit conditions.

Key Features:

• Amperage Rating: 80 Amps
• Fuse Class: Class J — compact, high-interrupting capacity design
• Voltage Rating: 600VAC
• Type: Time-delay (dual-element) for motor and compressor protection
• High Interrupting Rating: 200,000 AIC for superior fault protection

Class J fuses of this type are a common OEM specification in Carrier rooftop units, chillers, and commercial HVAC systems. The time-delay characteristic allows motors and compressors to handle normal startup inrush currents without nuisance tripping, while still responding quickly to true overload and short-circuit conditions. This fuse is a direct OEM replacement to maintain original equipment performance and safety ratings.
