LZCK2502-10 Epoxy resin three phase protection 5P20 zero phase current transformer is specifically designed for protection devices in power systems.
The 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 systems. It is widely used in compact fully insulated ring network switchgears and cable distribution boxes. The current 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.
100A Zero Phase Current Transformer: Applied to small current monitored circuits. When the monitored circuit fails, it can turn 100A input current into zero phase current ranging from 10mA to 1,000A and control the switching of circuits.
This zero phase current transformer detects the difference between the currents flowing in a number of conductors. The current flowing to a load must equal the current flowing back from the load. If this is not the case, a potentially dangerous residual current will be flowing somewhere in the installation.
●P1, P2 is primary polarity terminal, S1, S2 is secondary polarity terminal.
●P2, S2 is homonymous terminals (subtractive polarity).
