KLKD SERIES 10x38 FUSES
600 Vac/dc • 1/10 -30 A • Fast Acting
Specifications
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.
