1. Can the SFCT current transformer be customized for different fuse switch disconnectors?
Yes. The SFCT current transformer can be customized according to the fuse switch disconnector structure, busbar dimensions, mounting space, current ratio, and electrical requirements. Customers can provide drawings, dimensions, or existing samples for evaluation.
2. What current ratios and accuracy classes are available for the SFCT current transformer?
The SFCT can be manufactured with different primary and secondary current ratios according to project requirements. Various metering and protection accuracy classes are also available. Please provide the required current ratio, accuracy class, and burden so that we can recommend the correct specification.
3. What busbar sizes can the SFCT current transformer accommodate?
The suitable busbar size depends on the internal window dimensions and the available installation space inside the fuse switch disconnector. Please provide the busbar width, thickness, and surrounding mounting dimensions, and we can confirm the appropriate SFCT model or customize the structure.
4. Can the SFCT current transformer be used for both metering and protection?
Yes. Depending on the winding design, accuracy class, current ratio, and burden, the SFCT current transformer can be designed for current measurement, energy metering, monitoring, or protection applications in LV distribution systems.
5. What information is required to select the correct SFCT current transformer?
To select the correct SFCT current transformer, please provide the primary/secondary current ratio, accuracy class, rated burden, busbar dimensions, system voltage, frequency, and available installation space. A drawing or photo of the fuse switch disconnector is also helpful for confirming mechanical compatibility.
