The MCAN Molded Canister Fuse is a compact, lightweight EPDM molded rubber fuse enclosure package. MCAN fuse canisters are maintenance-free,
completely sealed and submersible. Designs are deadfront, using molded rubber to insulate, shield and eliminate exposed live parts. Units are ideally suited
for padmount, subsurface or vault applications, for systems through 28kV gndY–gndY. The MCAN Molded Canister Fuse will accommodate and has been
thoroughly tested with Hi-Tech

FX fuses. Contact Thomas & Betts before using fuses from other manufacturers.
Completely sealed and insulated

MCAN Molded Canister Fuse
EPDM molded rubber deadfront construction insulates,
shields and eliminates live parts
Fuses are fully sealed and submersible
Modular construction enables elbow connection or direct
attachment to equipment-mounted bushings
Neon voltage indicators (V2) attached to elbow test points
to provide quick and convenient blown-fuse indication
Various end fittings and bushings make for flexible installation
on switchgear, junctions, transformers, cable runs and taps
Replaceable fuse enables easy fuse replacement without full removal from installation
Current-limiting protection limits the system available fault current and dramatically reduces stresses on equipment
304 stainless steel mounting brackets and wall-mounted parking stands available to accommodate a wide variety
of mounting arrangements

Application Information
Construction: Submersible, corrosion resistant, fully shielded
Ambient Temperature Range: -30° C to 65° C
* Without fuse.
** The 15.5kV L-G rated fuses require at least 75% grounded load
to be applied on a 25kV system.
Note
: ­Fuse replacement requires the MCAN to be de-energized.
