Product Information:

Use the Kingsmill KP series of products for telephone and signal line protection for signals utilizing the KRONETM LSA-PLUS® 10-way connection blocks.

Features:

  • Remote signalling
  • Reversible installation
  • Biconnect terminals
  • Locking pluggable modules
  • Optical lifetime status indication

Benefits: No follow-through current, no leakage current, and coordinated range (install in close proximity to each other).

Standards: BS:EN 62305 (lightning protection) and EN 61643-11 (surge protection devices).

More Information:

Two Stages of Protection:
Standard KRONETM surge arresters only provide a single stage of protection which cannot prevent equipment from being exposed to excessive voltages during a surge event. The KP series of products utilize a two-stage protection approach that keeps the voltage let through to an absolute minimum.

Telephone and Signal Protection:
The KMKP-10 devices are designed for protecting PSTN and digital PABX signals with a maximum line voltage of up to 200V. They protect all common signaling systems.
