SCTK681D Series CE RoHS Split Core Current Transformer , Low Voltage CT For Energy Monitoring
Open-end current transformers are mainly used in power distribution system renovation projects, easy installation, no need to dismantle a bus, can also be live operation, does not affect the normal power consumption of customers, for the user transformation projects to save manpower, material resources, financial resources, improve efficiency.This series of current transformers can be used with relay protection, measurement and metering devices.
The SCTK681D Series current transformer shell is made of imported polycarbonate injection molding which is flame retardant and temperature resistant at 140℃, the iron core is made of oriented cold rolled silicon steel strip, and the secondary wire is made of high strength electromagnetic enameled wire. The product has the advantages of novel structure, beautiful appearance, convenient installation, small size, light weight, high accuracy and large capacity.
