PROMET 4300 is digital protection relay that provides various protectice functions for all voltages and current elements needed in power protection system selectively combined with high-speed operation by DSP, and enables to realize the compact configuration of switchgear, and that enables the electronic switchboard solutions by providing a variety of interface with upper system.
It also adopt a graphic LCD to provide various user convenience(Mimic, vetor diagram)
