PRODUCT INTRODUCTION
LZCK350-10 Split Core Current Transformer

LZCK series split core current transformer is suitable for current 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-SafeRing/SafePlus...and cable distribution boxes. The transformer can be directly installed at the inlet and outlet cables.The slice is imported silicon material. The semicircular ring core and secondary windings are vacuum poured by insulated resin.
