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.
