Surge limiter cartridge type V50-0-320 5093509

### Surge Protection – Reliability and Installation Safety

The V50-0-320 surge limiter insert is a key element ensuring the protection of electrical devices against the effects of sudden voltage increases. Designed to work with class 1+2 surge limiters, it effectively protects against damage caused by lightning strikes or other disturbances in the network. Mounted on a DIN TH-35 mm mounting rail, it provides easy and quick installation in electrical switchboards.

This model is distinguished by its high efficiency, guaranteed by an impulse current of 12.5 kA (10/350 µs) and a protection level of 1.4 kV. This means that it is able to neutralize even strong voltage pulses, minimizing the risk of failures and downtime of connected devices. Optical indication of operation allows for quick identification of the need for replacement after a surge.

Construction and application

The V50-0-320 insert is compatible with various network configurations, making it a universal solution for a wide range of applications. The possibility of use in non-standard network systems (TT, TN, IT, TN-C-S, TN-C) increases its flexibility and allows it to be adapted to specific installation conditions. A wire cross-section of up to 35 mm² allows connection of both single- and multi-strand wires, ensuring compatibility with most electrical installations.

The use of the V50-0-320 surge limiter is particularly important in places prone to frequent thunderstorms or in installations powering sensitive electronic devices – such as alarm systems, building automation or computer equipment. Thanks to its design and technical parameters, this insert meets safety standards and provides long-term protection of the electrical installation. Additionally, the compact size (1 module) allows you to save space in the switchboard.
