Introduce
The SFCT series current transformer is specifically engineered for integration inside switchable in-line fuse switch disconnectors and low-voltage distribution cabinets used by electrical distribution authorities. In these systems, the transformer provides accurate current measurement and protection signals required for feeder monitoring, load balancing, metering, and automation functions.
Its compact window-type design allows direct installation around busbars or insulated cables without requiring major structural modification to the switch disconnector housing. The SFCT ensures stable signal output even under varying load conditions and during switching operations, making it suitable for use in distribution feeder pillars, utility service cabinets, customer connection units, and compact LV switchboards.
Applications
- Industrial power system: used for remote disconnection of main power supply in elevator shafts and machine rooms
- High voltage system: achieving safe isolation in high-voltage digital control applications
- Automotive electronics: battery disconnect switch for vehicle electrical systems
- Process industry: application in equipment control in industries such as chemical, power, and petroleum
