Product Details

LZJC-10 Current Transformer for Small Switchgear is a current measurement device designed for 6~35kV air-insulated switchgear. It is widely used for current measurement, protection and monitoring in power systems. Especially for small switchgear, it is favored for its compact design and efficient performance.

Characteristic of structure

The iron core, the primary winding and the secondary windingare all enclosed in the epoxy resin casting body. The sign ofoutput terminal is Pi and P2. The output terminal of the secondarywindings(the first one, Measurement Class)is 1S1, 1S2, Theoutput terminal of the secondary windings (the second one,Protection Class)is 2S1, 2S2. The four holes below the casting arefor installing.
