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.

Direct earthing

Earth bonding is made using a DIN rail fixing clip.

Common mode / differential mode protection

The differential mode offers an improved protection efficiency.
