H1 SFC9-24KV Polymer Cutout Fuse – 24kV High-Voltage Overhead Line Protection Solution
In electrical distribution, a polymer cutout fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads.
The SFC9-24KV Polymer Cutout Fuse is designed for 24kV class systems and is available in 100A and 200A rated current versions.
Compared with porcelain cutout fuses, the polymer cutout fuse is lighter and also has efficient current transfer and higher interrupt capacities.
The SFC9-24KV features a breaking current of 10000A for the 100A version and 12000A for the 200A version.
It offers an impulse voltage of 150kV, power-frequency withstand voltage of 65kV, creepage distance of 540mm, weight of 4.5kg, and dimensions of 51x34x11.5 cm.
We make available these fuses in varied specifications to meet the clients’ different preferences in an efficient manner.
All dimensions, electrical ratings, mounting configurations, and fuse link options are customizable upon request.
For complete engineering drawings or specific tolerances, please refer to the original documentation or contact our technical team.
