Telecommunication Surge Protection Devices

Use telecommunication surge protection devices to protect your telecommunications lines against lightning strikes, voltage spikes, power surges, and other transients. These lines are often in highly exposed areas and left unprotected at the primary and secondary. You’ll find surge protection devices suitable for primary, secondary, and security applications below.
