Description
The Littelfuse KLK001 is a 1 Amp fast-acting midget cartridge fuse engineered for precise, reliable overcurrent protection in industrial and commercial electrical systems. Rated at 600V AC, it responds instantly to fault conditions — interrupting overloads and short-circuit currents before downstream equipment is damaged. The compact midget form factor makes it ideal for space-constrained control panels, while its high interrupting capacity ensures it stands up to the demands of tough industrial environments. The KLK series is a trusted choice wherever fast fault response is critical and inrush currents are minimal.
