Cable Protection Fuses
Mersen CP cable protectors are special purpose limiters which are crimped or bolted to cables to clear and isolate faults quickly, increasing the reliability of service entrance and distribution runs. They are current-limiting with a 200,000A interrupting rating, yet will carry low cable overloads which are handled by standard protective devices. Cable protectors are rated in terms of cable size and material (Al or Cu). Heat shrinkable (HS) tubing can be specified for field installation. For cables smaller than 4/0, class J fuses can be used.
