H1 SFC6-33KV USA Type Cutout Fuse – 36kV High-Voltage Overhead Line Protection Solution
In electrical distribution, a fuse cutout or cut-out 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 SFC6-33KV USA Type is designed for 36kV class systems and is available in 100A and 200A rated current versions.
It provides reliable electrical performance, high breaking capacity, and flexible customisation for various distribution project requirements.
The SFC6-33KV USA Type features a breaking current of 10000A for the 100A version and 12000A for the 200A version.
It offers an impulse voltage of 170kV, power-frequency withstand voltage of 70kV, creepage distance of 720mm, weight of 15.5kg, and dimensions of 63x38x14.5 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.
