Product Description
The Littelfuse KLK-1-1/2 (also listed as KLK01.5) is a 1.5Amp, 600V AC fast-acting “midget” (5AG / 10×38 mm) fuse — part of the KLK series designed for supplemental over-current protection in control circuits, lighting, HID/LED systems, small motors, and other low-current / modest-load applications without high inrush current.
This fuse offers high interrupting-capacity and current-limiting protection, making it a reliable choice for safely isolating overloads or short-circuit faults in compact circuit spaces.
