600 Vac/dc ? 1 / 10 -30 A ? Fast Acting from clipboard

Description

The KLKD fuse series is fast-acting with a high DC voltage rating. This family of Midget style fuses (10 x 38 mm) is used in solar combiner boxes and in circuits with DC fault currents up to 50,000 amperes. KLKD fuses are available in standard and board-mount configurations. In addition, the KLKD series has been designed to meet both the UL and IEC photovoltaic fuse standards. Littelfuse offers a wide range of ampere ratings to match specific requirements in a variety of applications.
