Description
The Littelfuse LFXV15 series fuse block and cover is
designed to hold 1500 V size 20 x 127 mm fuses rated
35–60 amperes. Suitable for photovoltaic systems (string
and high-capacity combiner boxes) with fault currents up to
50 kA.
With available ampere ratings up to 60 A, more strings can
be pre-combined in harnesses to reduce the number of
inputs into combiner boxes, thereby decreasing installation
time and labor costs.

Features/Benefits
 Dead-front cover design offers personnel protection
 Ventilated design keeps the fuse running cooler, even
at high ambient temperatures and current ratings, to
increase fuse longevity
 Narrower width accommodates more blocks in a panel
to maximize space
 Designed for easy fuse removal and replacement to
minimize maintenance time. No tools required
 35 mm DIN-rail mounting option for quick assembly
and installation
 Accepts both wire and busbar for added flexibility  Positive lock feature secures the fuse puller in the block
when the fuse is absent
