The LSA-PLUS surge suppressor protects telecommunication and data lines from harmful voltage spikes caused by lightning strikes, power surges, or switching transients. Designed to integrate seamlessly with LSA-PLUS connection systems, it offers quick, tool-free installation in distribution frames and junction boxes. Its compact, modular design allows for easy maintenance, with pluggable components and clear visual indicators for status monitoring. Ideal for use in telephone exchanges, data centers, and industrial networks, it ensures reliable performance and safeguards sensitive equipment.

Features

1. LSA-PLUS Terminal Compatibility: Specifically designed for use with LSA-PLUS connection blocks in telecom and data systems.
2. Signal Line Protection: Protects analog and digital communication lines from transient overvoltages and surges.
3. Tool-Free Installation: Easily plugs into existing LSA-PLUS blocks without the need for additional tools or wiring.
4. Low Insertion Loss: Maintains signal clarity and performance with minimal impact on transmission speed.
5. Fast Response Time: Activates within nanoseconds to divert surge energy before it reaches sensitive equipment.
6. Modular Replaceable Design: Allows for quick replacement of individual suppressor modules without disturbing other connections.
7. Space-Efficient Form Factor: Compact size fits neatly into crowded telecom cabinets or distribution frames.
8. Standards Compliance: Built to meet IEC and ITU-T recommendations for surge protection in communication systems.

Installation

1. Identify the LSA-PLUS Block: Locate the correct terminal block where the incoming telecom or data lines are terminated.
2. Power Down the System: For safety, disconnect or isolate the telecom equipment during installation.
3. Choose the Protection Pair: Determine which line pairs (e.g., Tip and Ring) require surge protection.
4. Insert the Surge Suppressor: Snap the LSA-PLUS surge suppressor directly into the terminal block slot above the line pair—no tools needed.
5. Ensure Proper Grounding: Verify that the terminal block is connected to a reliable grounding system. The suppressor discharges surges through this path.
6. Secure Cabling: Make sure all cables are properly seated and that no wiring is loose or stressed.
7. Label the Protected Lines: Clearly mark which pairs are surge protected for future maintenance or inspections.
8. Power Up and Test: Restore power or telecom connection and verify that all protected devices are functioning normally.
