OBO Bettermann OBO LightningController MCF 351 FS440

The OBO LightningController MCF 351 FS440 is a highly advanced accessory for distribution cabinets, specifically designed for lightning protection in electrical systems. It meets the requirements of DIN EN 62305 (IEC 62305) and provides an effective Type 1 lightning current arrester. With a lightning current discharge capacity of 35 kA (10/350) per pole and a network-following current extinguishing capability of 50 kAeff, this device ensures reliable protection against overvoltages. The encapsulated, non-blow-out spark gap arresters are optimized for use in distribution enclosures and feature a disconnection device with optical indication, allowing for easy monitoring of operational status. Additionally, a remote signaling system with a potential-free changeover contact is integrated, facilitating the monitoring and maintenance of electrical systems.
