    This offer is designed to answer all the possible installations due to site RM6+ installation constraints with only 1 reference. Type tested in a COFRAC certified laboratory for >Electro-Magnetic Compatibility>Mechanical = Choc, Mechanical vibration, Signe Sweep Seismic Reach and RoHs conformity Self-powered protective relay - The solution provides protection against phase-to-phase faults and earth faults.- The solution is a self-powered relay, energized by the current sensors; it does not require any auxiliary source.It actuates a Mitop release. Phase protection The phase protection has two separately adjustable settings:- the low setting may be chosen with definite time or IDMT. The IDMTcurves are in compliance with the IEC255-3 standard. They are of the standard inverse, very inverse and extremely inverse types. The low setting may also be used with the RI curve.- the high setting is of the definite time type. Earth protection The earth fault protection operates by residual currentmeasurement: it uses the sum of the sensor secondary currents. Like phase protection, earth protection has two separately adjustable settings.
