RGU-100A, Residual current relay for WGC Transformer, ultraimmunized type A, 3 modules and screen
The RGU-100A is a type-A ultraimmunized earth leakage protection and monitoring relay that is compatible with the earth leakage transformers in the WGC range.
The device measures, calculates and displays the true RMS value of the residual current by using a residual current input from an external measurement toroidal transformer in the WGC series.
The RGU-100A can be used to program and adjust all the parameters required to obtain complete protection and control of the installation.
The RGU-100A offers smart residual current protection.
Thanks to its design characteristics, this device provides the most complete type-A protection to ensure the safety of people and continuity of supply in electrical installations.
Its ultraimmunized system guarantees that a trip will only occur when it is absolutely necessary, avoiding financial losses due to unwanted trips.
Being able to view the instantaneous leakage value on the display, together with the pre-alarm indications, provides information on the status of the lines they protect so that proper preventive maintenance can be done.
In addition, the RGU-100A version with RS-485 communications, in conjunction with PowerStudio software, adds centralized real-time monitoring and logging for later analysis.
