Surge Protection Module LSA LSA-ARR-YM — 10 pairs, 3-pole

Surge Protection Module LSA LSA-ARR-YM — 10 pairs, 3-pole is a protective unit developed for overvoltage suppression in telecommunication and low-voltage distribution installations. Designed to mount on LSA-style termination blocks, the module provides coordinated surge diversion across three conductors and supports protection of up to ten paired lines. The compact format allows integration into distribution frames and telecommunications cabinets where multi-line protection and controlled discharge paths are required.

Advantages

The module offers multi-line, three-pole protection in a single unit and is compatible with LSA termination systems for straightforward installation. Its coordinated diversion characteristics reduce the risk of secondary damage to connected equipment by directing surge energy to the protective earth. The ten-pair capacity enables consolidated protection for multiple circuits, lowering wiring complexity and saving rack space compared with single-line protectors.

Suitable for

• Telecommunication distribution frames and patch panels
• Low-voltage signal lines in commercial or industrial networks
• Multi-pair telephone, DSL or data circuits requiring common-earth surge protection
• Equipment rooms and telematics cabinets where compact, rack-mounted protection is needed

Key specifications

• Configuration: 3-pole protection for each protected pair
• Capacity: protection for 10 paired lines
• Mounting: designed for LSA-style termination block connection
• Function: coordinated surge diversion to protective earth
• Application voltage range: suitable for telecommunication and low-voltage signal systems
• Form factor: compact module compatible with distribution frames and cabinets

How to use

Install the module on the corresponding LSA-style termination block according to the system layout and wiring plan. Connect each incoming and outgoing line pair to the module contacts so that the protected conductors are routed through the module and a secure protective earth connection is established. Ensure that the protective earth conductor is of adequate size and continuity to allow proper surge diversion. Verify mechanical fixation in the distribution frame and test line continuity before returning circuits to service.

Usage recommendations

Place the module in close proximity to the termination block and maintain a short, low-impedance protective earth connection. Periodically inspect the module and associated grounding for signs of corrosion, loose connections or surge events that may have degraded protective capability. When used in critical installations, consider coordinated protection levels across upstream and downstream protective devices to ensure appropriate protection performance.
