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
