I N T R O D U C T I O N Scope and liability This document describes the functions, the technical data of NA10 devices; instructions for mount- ing, setting and commissioning are included. This manual has been checked out, however, deviations from the description cannot be completely ruled out, so that no liability in a legal sense for correctness and completeness of the information or from any damage that might result from its use is formally disclaimed.
• Test label with following informations: data, serial number and test operator signature. Environment The NA10 device must be employed according to the environment conditions shown (see technical data). In case of different environment conditions, appropriate provisions must be provided (conditioning system, humidity control, etc...).

G E N E R A L Preface The relay type NA10 can be used in radial networks as feeder or power transformer protection. In solidly grounded systems the residual overcurrent protection can be used on feeders of any length, while in ungrounded or Petersen coil and/or resistance grounded systems, the residual over- current protection can be used on feeders of small length in order to avoid unwanted trippings due to the capacitive current contribution of the feeder on external ground fault.
• USB front serial port (local communication for ThyVisor). • Real time clock with super capacitor backup. The most significant constructive features of the NA10 protection relay are: • Galvanically insulated input and output circuits (communication and binary circuits included).
Note 3 The nominal current settings doesn’t concern the protection elements; they must agree with hardware setting (dip-switch 1 A or 5 A) . Note 4 1 - 5 A selection is meaningful for standard CTs versions; the computed residual current is employed for NA10 protection relays equipped with...
