DESCRIPTION

Citel DL Series has been designed to protect telephone and data lines against lightning surges and electrical transients. Its large power handling and fast response time will protect your sensitive equipment against the worst lightning surges.

It uses state of the art multi-stage circuitry which consists of heavy duty three element gas tubes and solid state diodes that automatically reset after every electrical surge.  Under the most severe conditions, the Citel DL Series will fail short leaving your equipment fully protected.
