Preface
the SIF5600 type digital protection relay provides protection for machinery and electricity lines
against overloads, short-circuiting between phases and ground faults, including phase overcurrent
and residual current functions.
Particularly, it may be used for the general protection of appliances connected to the MV distribution
grid in compliance with eNeL DK5600 specifications for applications envisaging maximum current
50-51 and ground fault 51N protective functions.
the setting and reading methods may be performed with the aid of a Personal computer with sup-
porting bundled Software (along with the thySetter) or by means of MODBUS® rS485 serial commu-
nication; for those models fitted with displays, all the above mentioned operations may be performed
with the aid of the front fitted keypad.
the relay is available in a number of versions distinguished by the operational range of the auxiliary
supply voltage, the presence of an alphanumeric display, the number of phase current inputs and
type of mounting.
