Product Information:
Use the Kingsmill KP series of products for telephone and signal line protection for signals utilising the KRONETM TM is a smal TM like to the power of 2 in notation, it means trade mark 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: EN 61643-12 (surge protection devices), AS/NZS 1768
More Information:
A surge or lightning protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment.
Two Stages of Protection:
Standard KRONETM TM is a smal TM like to the power of 2 in notation, it means trade mark 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 utilise 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 signalling systems.
