OVERVIEW:

• The CBS-4 earth leakage unit associated with the transformers of the WG / WGC Series allows smart earth leakage protection. Its design features guarantee maximum security and continuity of the electrical service, avoiding unwanted tripping. Showing the value of the leak instantaneously on the display with the pre-alarm indications provides information about the state of lines being protected, thus allowing the implementation of an adequate preventive maintenance approach. In addition, version CBS-4 C with RS-485 communications is used with the PowerStudio software, which allows the centralized supervision of the system in real-time, with a record log that can be analyzed later on.

Feature:

• Unit equivalent to 4 earth leakage protection networks. 4 independent programmable relays available
• Four inputs to connect the external toroidal transformers of the WG
• Superimmunized Type A relay with high-frequency current filtering and high immunity. Monitoring in true root mean square (TRMS)
• Reduced size, with 3 modules
• 5 independent programmable outputs (4 earth leakage trip relays and 1 pre-alarm trip).
