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. Need help to find the best surge protection solutions? The Surge Protection Device Selection Tool helps you select SPDs for a broad range of applications from small data rooms to enterprise data centers.
