TYPES Y, Z
NETWORK PROTECTOR
FUSES AND DURICOMP™
ENCLOSURES
Type Z Network Protector Fuses are designed
to coordinate with the fusible sections of the
Limiters as well as the Protector characteris-
tic itself. A DURICOMP™ enclosure is
designed especially to form an arcing cham-
ber for these fuses and contains no asbestos.
The hole spacings in the tongues of these
fuses are such that they will fit standard
Network Protectors. See Time Current char-
acteristic curve below. The Fuse element and
the housing must be purchased separately.
