    This paper presents a design and implementation of two current relay prototypes. The first one is based on FPGA, it protects against over-current, phase loss and locked rotor. This design is implemented, downloaded and tested on Altera Flex 10k10LC84-4 device. The second prototype is microcontroller based Multi Function Relay, it protects against over current, undercurrent, phase loss, locked rotor, phase unbalance and ground fault. This design is implemented and tested on Atmel microcontroller ATMega16PC0351I. Finally, both prototypes specifications were referenced to SMWAHA EOCR-Schneider Electric protection relays EOCR-SS and EOCR-3EZ respectively according to the European and Korean standards. � 2004 EEE.
