SPFJ Series 1000vDc Solar Fuse
Description
The SPFJ Series is the smallest 1000VDC
125-450A photovoltaic fuse available in the
market. The SPFJ series is manufactured
in Class J case sizes that allows for both
fuseholder and busbar mounting configuration.
The SPFJ meets both UL and IEC requirements.
Features & Benefits
• Meets both uL and IEC photovoltaic standards
• Small footprint reduces panel size
• Full-range PV time-current characteristic
• Flexibility of fuseholder or busbar mounting
• Higher amperage solar fuses in standard sizes
• uL listed Class J branch and feeder circuit rated
KlKD Series 600vDc/600vAc Fuses
Description
The KLKD fuse Series is fast-acting and has
a high DC voltage rating. This family of Midget
style fuses (10x38mm) is used in solar combiner
boxes and in circuits with DC fault currents up to
50.000A. KLKD fuses are available in standard
and board-mount configurations. As PV systems
have grown in size, so have the electrical
characteristic requirements. 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.

SPF Series 1000vDc Solar Fuse
Description
The SPF Solar Protection Fuse Series has
been specifically designed for the protection
of photovoltaic (PV) systems. This family of
Midget style fuses (10x38mm) can safely protect
PV modules and conductors from reverseovercurrent
conditions.
As PV systems have grown in size, so have
the corresponding voltage requirements. This
increase in system voltage has typically been
intended to minimise power loss associated with
long conductor runs. Standard circuit protection
devices are not designed to completely protect
photovoltaic panels. however,the SPF Series is
uL Listed to safely interrupt faulted circuits up
to this demanding voltage level. Littelfuse offers
13A ratings to match specific requirements in a
variety of applications.
lDc Series class l
Description
The 600VAC/DC rating of the LDC Series
can be used on either the AC or DC side
of a photovoltaic system.
