CBS-4, Station with 4 programmable residual current relays, type A
The CBS-4 multipoint residual current system associated with the WGC / WGS transformers offers smart residual current protection. Its design features guarantee maximum security and electrical service continuity, avoiding unwanted tripping. Viewing the instantaneous leakage value on the display, together with the prealarm indicators, makes it possible to obtain information on the status of lines to be protected, and to perform adequate preventive maintenance.
In addition, version CBS-4 C features RS-485 communications and, with the PowerStudio software, offers centralised supervision in real time, as well as keeping a log of historical data for future analysis.
