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.
