Especially developed for indication and supervision of the single-phase circuit, replaces an analogical ammeter, reducing installation manpower and optimizing the used one of spaces in the panel. Ideal for protection of single-phase networks is monitored and generally to own alarm superior and inferior. Protection of the parameters of programming by password.
