A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock.Injury may still occur in some cases, for example if a human falls after receiving a shock. In the United States and Canada, the device is called a ground fault circuit interrupter (GFCI), ground fault. Earth Leakage Circuit Breaker (ELCB) Earth Leakage Circuit Breaker (ELCB) is a device used to directly detect currents leaking to earth from an installation and cut the power and mainly used in TT earthing systems.. As we known,Molded Case Circuit Breaker main function is protection device from overload current and short circuit.It also have a several attachment device for additional protection that we can combine with MCCB. Common accessories used for MCCB such as phase insulation barrier,Shunt trip,Under voltage trip device,rotary handle and change over system.It can provide more protection .

A transformer is a static electrical device that transfers electrical energy between two or more circuits.A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force (emf) or "voltage" across a second coil wound around the same core. Electric power can be transferred between the two coils, without a metallic. Any 4/20mA field device using 2 wires is probably going to be "loop powered", ie it derives its power from the first 4mA of the signal. There are many other devices that are separately powered but still emit a 4/20mA signal that can be picked up by a DCS input card..
