Product Description

LZCK2500-10 SELECTING PRECISION 35KV 50/5A 5P20 RELAY SPLIT CORE ZERO PHASE CT CURRENT TRANSFORMER


LZCK series 5P20 split core zero phase ct 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-Safe Ring/Safe Plus...and cable distribution boxes. The current 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.
