Surge limiter insert type V20-0-280 5095364

### Surge protection in electrical installations

The V20-0-280 surge limiter insert is a component designed to protect electrical devices from the effects of surges that can occur due to lightning strikes or failures in the power grid. It is a key element in ensuring the safety and reliability of electrical installations, both in residential and industrial buildings. This product, manufactured by OBO BETTERMANN, is characterized by high efficiency and durability.

### Construction and application

This insert is a replaceable element, designed for mounting in enclosures of type 2 surge limiters. Its task is to quickly dissipate excess energy to ground, minimizing the voltage at the terminals of protected devices. This protects sensitive electronic components from damage. The use of the V20-0-280 surge limiter is particularly important in places prone to frequent thunderstorms or powered by an unstable grid. It is compatible with various network systems – TN, TN-S, TT and TN-C – making it a universal solution for many installations.

### Key features and benefits

* **High protection efficiency:** Rated discharge current up to 20 kA (peak value) and a protection level of 1.3 kV (L-N) guarantee effective protection against surges. The maximum discharge current reaches even 40 kA, providing additional safety in the event of strong discharges.

* **Versatility:** Compatibility with various network systems (TN, TN-S, TT, TN-C, TN-C-S) allows for use in a wide range of electrical installations.

* **Optical indication:** A built-in optical indicator informs about the operation of the insert and the need for its replacement after a surge – this facilitates diagnostics and maintenance of the installation.

* **Large wire cross-section:** Maximum cross-section of flexible and stranded wire up to 352 mm² allows connection of wires with a large diameter, which is important in installations with a high current load.

* **Compact dimensions:** The insert has a size of 1 module, allowing for easy installation even in tight electrical panels.

* **Safety:** Made of self-extinguishing plastic (UL 94 V-0), which increases safety and minimizes the risk of fire spreading in the event of a failure.

* **Compliance with standards:** The product meets the requirements of EN 61643-11 and IEC 60364-4-44 standards, which guarantees its quality and reliability.

* **N-PE protection up to 20kV**: Additional protection against surges between the neutral and earth conductors increases the safety of the entire system.

Choosing the right surge limiter insert is an investment in the safety and durability of the electrical installation. V20-0-280 is a proven product from OBO BETTERMANN, which provides effective protection against the effects of surges and minimizes the risk of failure and damage to electrical equipment.
