LZCK350-10 100/5A Epoxy Resin Cast Split Core Current Transformer
LZCK series resin split core current transformer is suitable forcurrent measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system.It is widely used in compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe plus...and cable distribution boxes.The transformer can be directly installed at the inlet andoutlet cables.The slice is imported silicon material. Thesemicircular ring core and secondary windings arevacuum poured by insulated resin.
