SURGYS RS-3, mA-3, TEL-3
Low current surge arresters for telecommunication and data networks
For protection against transient overvoltages of equipment connected to telecommunication and data transmission networks the SURGYS range includes 3 surge arrester models:
• SURGYS RS-3.
• SURGYS mA-3.
• SURGYS TEL-3.
Advantages
Versions 1 pair or 2 pairs (model “x2”)
Ultra-compact design if multi-pair protection is needed.
Plug-in modules
Rapid maintenance for end of service life modules.
End of service life indicator
Indication is achieved through line interruption.
