  ESP KT1

Ideal as protection for PBX telephone exchanges, ISDN and other telecom equipment with LSA-PLUS disconnection modules; specifically for PSTN such as dial-up, lease line, DSL, broadband, and U interface ISDN lines, Furse offers ESP KT1. These units present an outstanding electronic systems protection.

  
ESP KT1 units furnish low cost protection for single lines. It has low let-through voltage between all sets of conductors. As a result of series of deliberate tests in compliance to ITU K20 standards, it is capable of multiple strike protection, with the ability to protect against at least ten 5kA transients.
 

Safe and reliable, the applications are based from the Telcordia and ANSI qualifications. ESP KT1 contains resetable over current protection and are rated for power cross faults.

The ESP KT1 units are module type recommended in telecommunication and call center companies, large building and offices, as protection for the telecommunication lines.
