High Voltage Split Core CT Current Transformer - 11KV 33KV LZCK322-10

Supplier: Beijing GFUVE Electronics Co.,Ltd.

The High Voltage Split Core CT Current Transformer is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system.

Price Guide (Inc GST): POA

The LZCK322-10 High Voltage Split Core CT Current Transformer is widely used in compact fully insulated ring network switch gears such as ABB-Safe Ring/Safe Plus and cable distribution boxes. The transformer can be directly installed at the inlet and outlet cables. The slice is imported silicon material. These micircular ring core and secondary windings are vacuum poured by insulated resin.
