•    2.5 sqmm Terminal Interface

With the rapid advance of electronics technology moving towards the miniaturization of large scale integrated circuitry, it inevitably increases the vulnerability of electronics components or systems being damage by electrical surge caused by lightning or power line fault. For the Telephone Switching Technology, the old Electromechanical X-bar switches have been replaced with the more capable and intelligent switches which integrate with a lot of advanced electronics ICs. Therefore, more protection against surge is needed than the old system.

SurgeGuard’s Telephone Protection Module, TPM-TMN, has been specially developed to match the protection requirement of new telephone system technology using sensitive electronics components. By using the multi-stages hybrid design technique instead of the traditional single stage gas tube arrester, TPM-TMN offers greater protection capability, higher surge rating, faster response time and longer operational life.
TPM-TMN is designed to connect directly to subscriber line interface using Terminal Block. By separating the Terminal Base (TB) module and Protection Cap (PC) module, it makes it easy to replace failed Protection Cap without any re-wiring.
