Surge arrester, 3p Type 2 (class C) type V20-3+FS-280 5095283

Electrical installation protection with surge limiters

This three-pole Type 2 surge limiter, designated V20-3+FS-280, is a key element ensuring the safety and reliability of the electrical installation. Designed to work with TN-C, TN-S and TN-C-S networks, it effectively protects against the effects of surges that can damage sensitive electronic devices. Its compact housing, occupying 3 modules on a TH-35 mm DIN rail, facilitates mounting in main and sub-distribution boards.

This limiter is characterized by its high efficiency – it withstands a surge current of 40 kA (8/20 µs) per pole, making it an ideal solution in places exposed to frequent and strong surges. Additionally, it has a built-in contact for remote failure indication (FS), allowing for quick identification of the need for cartridge replacement. This means not only increased safety, but also minimized downtime of the installation.

Application and benefits for professionals and users:

• Versatility: Compatible with various network configurations (TN-C, TN-S, TN-C-S) – one limiter fits many installations.
• High performance: The ability to dissipate discharge current up to 40 kA provides effective protection even in the event of strong surges.
• Status indication: Built-in contact for remote failure indication facilitates monitoring the device status and quick response in the event of a failure.
• Safety: Mechanical locking of cartridges protects against accidental ejection during operation and against the influence of vibrations.
• Easy installation: Compact dimensions (3 modules) and mounting on a standard TH-35 mm DIN rail simplify installation.
• Durability: The housing made of self-extinguishing plastic (UL 94 V-0) provides fire resistance and long-term operation.
• Short-circuit protection: Short-circuit strength at the level of 50 kA provides additional safety for the installation.

The V20-3+FS-280 limiter complies with VDE 0100-443 (IEC 60364-4-44) standards, guaranteeing its high quality and reliability. Thanks to this, you can be sure that your electrical installation is properly protected against the effects of surges, and electronic devices operate without interference. Wire cross-section up to 35 mm² allows connection of both rigid and flexible wires. 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.
