Surge arrester, 4P Type 1+2 (class B+C) type V50-3+NPE-150 5093454

Protection of electrical installations and devices – Type 1+2 surge arrester

This four-pole surge arrester class B+C is a key element ensuring safety in electrical installations. Designed to protect against the effects of lightning strikes and fast voltage transients, it effectively minimizes the risk of damage to equipment and system failures. It is an ideal solution for both installations in residential and industrial buildings.

This surge arrester can be used in various network configurations – TT, TN, TN-S and TN-C-S, making it a universal choice for most installations. Mounting is done on a standard DIN TH-35 mm rail, which facilitates integration with existing infrastructure. The compact size (4 modules) allows you to save space in the distribution box.

Characteristics and benefits

• Versatility: Compatible with TT, TN, TN-S and TN-C-S network systems. Allows use in a wide range of installations without the need for modifications.
• High efficiency: The ability to discharge impulse currents up to 12.5 kA (10/350 µs) per pole provides effective protection against overvoltages. The protection level of 0.8 kV for L-N and 1.5 kV for N-PE guarantees a high level of safety.
• Status indication: Optical indication of operation facilitates quick identification of damage and the need to replace the insert.
• Safety and durability: Made of self-extinguishing plastic (UL 94 V-0) provides fire resistance and long-term reliability.
• Practical mounting: Mounting on a DIN TH-35 mm rail is simple and quick, which translates into time savings during installation. The maximum wire cross-section of 35 mm² allows connection of wires of various thicknesses.
• Short-circuit protection: The ability to extinguish the follow current is 0.1 kA, which further protects the installation against the effects of short circuits.

This surge arrester meets the requirements of VDE 0185-305 (IEC 62305) regarding equipotential bonding in lightning protection, which confirms its high quality and compliance with applicable regulations. It is an investment in the safety and reliability of your electrical installation and connected devices.
