Edco MEGA-TEK 25 Series
Telephone Circuit Protection AMP-Type 25-Pair
The Edco MEGA-TEK 25 Series surge suppressor installs directly inline with
existing AMP-TYPE 25 pair connectors. The close proximity to the KSU/PBX
preserves the Edco MEGA-TEK’s response time, clamping level and ground
reference by reducing lead lengths.
The Edco MEGA-TEK’s unique design maximizes surge suppression performance
while reducing hardware and labor costs to install. The Edco MEGA-TEK is a
UL 497A telephone secondary protector. The product is available in
3
application specific models.
