Brand description Thytronic Protection Relay Products

Pro-N Intelligent Electronic Devices

The family is the Thytronic last generation of protective devices built on a common platform.

The compact size, the various assembly possibilities and the availability of measuring inputs suitable for 1 A and 5 A rated current, enable the relays to be adapted to different system layouts. It represents the ﬁ nal solution for the overall protection of distribution, utility substations and industrial networks whatever the voltage level.

	SMART line Protection Relays
	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 overcurrent 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.

S-Series

The relays of the S serie combine the semplicity in programming with a high degree of reliability and flexibility. Designed in accordance with Italian and International standards, the S serie devices are housed inside plastic cases suitable for various kinds of assembly (flush, projecting or 19" - 4U rack mounting). Some of these products shall be no more available.
