Surge arrester, 4P Type 1+2 (class B+C) type V50-3+NPE+FS-150 5093462

Protection against overvoltage in your installation

This four-pole type 1+2 surge protector is a key element in protecting the electrical installation from the effects of lightning strikes and other overvoltages. It provides comprehensive protection for both buildings equipped with an external lightning protection system and those without, meeting the requirements of VDE 0185-305 (IEC 62305) standards for potential equalization.

This surge protector effectively dissipates surge currents of up to 12.5 kA per pole, and up to 50 kA (10/350 µs) in total, protecting connected devices from damage. The design with replaceable cartridges with a dynamic disconnecting device and optical damage indication facilitates maintenance and quick identification of the need for replacement. Mechanical locking of the cartridges protects against the effects of vibration and provides voltage coding, minimizing the risk of incorrect installation.

Application and benefits:

• Versatility: Designed for TN-S, TT and TN-C-S networks, making it a universal solution for different types of installations.
• High efficiency: The ability to dissipate surge currents up to 50 kA guarantees effective protection against strong overvoltages.
• Easy diagnostics: Optical damage indication allows for quick problem location and cartridge replacement.
• Safety: Mechanical locking of the cartridges protects against accidental ejection during operation.
• Durability: The housing made of self-extinguishing polyamide (PA UL 94 V-0) provides resistance to mechanical damage and high temperature.
• Mounting: Mounting on a 35 mm top-hat rail is simple and quick, which translates to time savings during installation.

This surge protector is ideal for both professional installers who value reliability and ease of installation, and for end users looking for comprehensive protection of their electrical devices. By using this surge protector, you can significantly reduce the risk of failures caused by overvoltages, and thus avoid costly repairs and downtime. Remember to select the correct overcurrent protection (maximum 160 A gL/gG) to ensure optimal protection.
