H1 SFC7-33KV Nigeria Type Cutout Fuse – 33kV 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 SFC7-33KV Nigeria Type is designed for 33kV 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 SFC7-33KV Nigeria Type features a breaking current of 8000A for the 100A version and 10000A for the 200A version.
It offers an impulse voltage of 170kV, power-frequency withstand voltage of 70kV, creepage distance of 820mm, weight of 27.5kg, and dimensions of 68x17x15 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.
