EFB-Elektronik Módulo de proteção contra sobretensões LSA 2/10 até 10DA 8x13

The EFB-Elektronik LSA Overvoltage Protection Magazine 2/10 to 10DA 8x13 is a high-quality surge protection module designed for telecommunication and data lines. It provides reliable protection against overvoltages induced by lightning or switching operations, ensuring the integrity of your network infrastructure.

Advantages

This protection magazine offers robust protection with gas discharge tubes (GDT) rated for up to 10 kA per wire (8/20 µs) and 2.5 kA per wire (10/350 µs). Its compact 8x13 mm GDT design allows for easy integration into existing LSA connection strips. The module is flame-retardant and operates over a wide temperature range, making it suitable for harsh environments.

Suitable for

• Telecommunication lines (e.g., telephone, ISDN, DSL)
• Data transmission lines (e.g., Ethernet, RS-485)
• Protection of sensitive equipment in telecom cabinets and distribution frames
