Littelfuse JTD050ID Class J Fuse 20kA 300 VDC

The Littelfuse JTD050ID Class-J Fuse protects electrical circuits by interrupting current flow when overload or short-circuit conditions occur. Rated for 300 VDC with a 20 kA interrupting capacity, it reacts quickly to excessive current by melting its internal element and opening the circuit. Mount in control panels, power distribution units, and refrigeration equipment where circuit protection is required for motors, compressors, and control electronics inside HVAC systems. Fast-acting interruption assists with limiting electrical fault impact, reducing stress on connected wiring, and isolating damaged sections during abnormal current conditions within powered systems.
