CobiNet LSA overspanningsbeveiligingsmagazijn 2/10, 2-polige afleider, 10 paren 104241

Protect 10 telecommunication pairs with a single module: this LSA overvoltage protection magazine uses 2-pole gas discharge tubes to divert surges up to 10 kA per wire, keeping ISDN, DSL, and POTS lines safe from transient overvoltages.

Overview

Designed for direct plug-in onto LSA disconnection and connection strips, the CobiNet 104241 provides centralized surge protection for up to 10 pairs (20 wires). Each pair is protected by a 2-pole gas discharge tube with a DC sparkover voltage of 230 V ±20% and impulse sparkover below 700 V, ensuring quick response to fast-rising transients. The flame-retardant plastic housing withstands operating temperatures from -20°C to +70°C.

What stands out

• High discharge capacity: 5 kA nominal, 10 kA maximum per wire (8/20 µs waveform)
• Low capacitance <1.5 pF preserves signal integrity for high-speed data
• Insulation resistance >10 GΩ minimizes leakage
• Compatible with standard LSA-PLUS strips for easy installation
