Product Description

LZCK2502-10 Epoxy resin three phase protection 5P20 zero phase current transformer For protection device

LZCK2502-10 protection 5P20 zero phase 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.

100A Zero Phase Current Transformer The 100A zero phase current transformer is applied to small current monitoredcircuit. When the monitored circuit fails, it can turn 100A input current into zero phase current ranging from 10mA to 1,000A and control theswitching of circuits.

Zero phase current transformer which detects the difference between the currents flowing in anumber of conductors. The current flowing to a load must equal the current flowing back from theload. If this is not the case, a potentially dangerous residual current will be flowing somewhere in theinstallation.
