Microprocessor-Based Control
Wide Current Setting Range
Advanced 32-bit ARM Core MCU provides precise measurements and calculations, maximizing relay stability and reliability.
Rogowski CT prevents issues with magnetic flux saturation,
enabling a high degree of measurement accuracy.
˙ Current settings can be set from 0.5 A to 60.0 A in a single device
without additional setting; current settings of 0.125 A and 0.25 A
are possible by changing the CT number of turns, with a rated
current setting of up to 2,000 A possible with the external CT.

Multiple Protection Functions
Key protection function provide a full suite of basic motor protection.
˙ Over-current protection provides stable motor protection according to the load characteristics for definite time, inverse time and
thermal inverse time.
˙ A double layer of ground fault protection is provided by measuring zero current and residual current (Ground Fault Detection Current
100 mA to 60.0 A) (Earth Leakage Model of Normal Type, Advanced Type)
˙Up to 1,500 % True-RMS instantaneous protection function (Instantaneous Model of Normal Type, Advanced Type)
