3) Option of both Modbus & Profibus industrial communication protocols
4) Zigbee offers wireless monitoring parameters of Matrix releases & supplementary modules
2 4
5) Wide range of Overload protection curves (such as I t, I t, SI & LI/VI) offer precise co-ordination with large
variety of electrical loads
6) Option of Enabling/Disabling each protection function offers greater flexibility in designing the overall
protection system
7) Directional & Double Short-circuit protection
8) Password protection in releases prevents unauthorized access to protection release
9) Unique O-LED display offers better contrast & wider-viewing angle
10) Ease of parameterisation through Configurator modules
11) Dual time-based set group protection provides the option of setting two sets of protection curves
12) Front connector for hand-held testing of release
13) Soft-rating plug offers precise protection of electrical system at lower value of system currents
14) Query button for last trip information furnishes the “Trip Info” details such as cause of tripping, date and
time stamping of tripping
