DfC series

Dead-front fuse Covers

Mersen DFC dead-front fuse covers snap onto individual fuses installed in
fuse blocks, covering exposed live clips and terminals, reducing accidental
contact by personnel. They are sized to fit Mersen HP6J Class J and
HP10M or HP6M midget PV fuses for increased safety and (optional)
open-fuse indication. All DFC dead-front fuse covers are reusable when a
fuse is replaced – simply detach from the open fuse and re-attach to the
new replacement fuse. On indicator models, an orange indicator light will
illuminate to indicate an open fuse. DFC fuse cover ends can be easily cut to
accommodate existing wiring, safety switches or special installations. A blank
label is provided with each DFC to write in circuit or fuse information.
