Back-up current-limiting fuses fuses for protection of transformers and distribution systems.

Beyond our line of ANSI / IEEE current-limiting fuses, Mersen offers a full line of medium voltage fuse links according to the IEC standards. Among them, the back-up current-limiting fuse-links designed according to IEC 60 282-1 and meeting DIN 43 625 fuse-link dimensions. These fuse-links' operating range is between their minimum interrupting rating (I3) and their maximum interrupting rating (I1). When necessary, we offer these fuses with a controlled power dissipation (CPD) feature. These type CPD fuse-links, prevent overheating of the fuse compartment when installed in conjunction with a load break switch.

Features:
  • Conform to IEC 60-282-1 which is identical to German standard VDE 0670T4
  • Conform to DIN 43 625: High voltage fuse-links rated voltage 3,6 to 36kV
  • Blown-fuse indicator: The strikers of the MV fuse-links mentioned here have an effective length of 27mm and are a “medium type” This classification results from the energy released by the striker during the first 20 mm of ope rating distance
  • The initial force is about 80N and the force at the end of the cour se (27mm) is 15N
Ratings: 1 to 200A, 3 to 36kV, 20 to 63 kA I.R. AC
