Surge arrester, 2P Type 2 (class C) type V20-2-280 5095162

Surge protection for your installation

This two-pole type 2 surge protector, designated V20-2-280, is a key element in protecting the electrical installation from the effects of sudden voltage spikes. Designed to work with TN, TN-S and TN-C networks, it effectively protects electrical devices from damage caused by atmospheric surges or network disturbances. Its compact size – only 2 modules – allows for easy mounting in a distribution board.

Functionality and application

This surge protector is primarily used in main and sub-distribution boards, where it provides potential equalization and protection against surges. Its task is to dissipate discharge energy up to 20 kA (peak impulse value 8/20 µs), and even up to 40 kA, which guarantees high efficiency. The L-N protection level is 1.3 kV, and N-PE as much as 20 kV, providing comprehensive protection against various types of surges. Mounting is done on a standard DIN TH-35 mm rail.

Key features and benefits

• High efficiency: Ability to dissipate discharge current up to 40 kA (8/20) per pole thanks to the use of high-performance varistors.
• Versatility: Designed to operate in TN, TN-S and TN-C networks, making it compatible with most electrical installations.
• Optical signaling: Built-in optical indication of the device status informs about its operation and any need to replace the insert.
• Safety: Made of self-extinguishing plastic (UL 94 V-0), which increases safety.
• Easy installation: Compact dimensions (2 modules) and mounting on a DIN TH-35 mm rail facilitate installation.
• Wire protection: Maximum wire cross-section of 35 mm² allows connection of wires of different thicknesses.
• Durability: Short-circuit strength (Isccr) is 20 kA, ensuring resistance to damage during network short circuits.

This surge protector is a reliable solution for anyone who cares about the safety of their electrical installation and the protection of valuable electronic devices from the effects of surges. It provides peace of mind and minimizes the risk of costly failures caused by sudden voltage spikes.
