Surge protective device Type 1+2+3 50kA 1+1p DS252VG-300/G C3403

Electrical installation protection with surge arresters DS252VG-300/G

The DS252VG-300/G surge arrester is an advanced device designed to protect electrical installations from the effects of atmospheric and switching surges. Its design and parameters make it indispensable in both residential and industrial buildings. This model combines three classes of protection (Type 1+2+3), providing comprehensive defense against various types of interference.

Universal application and high efficiency

This arrester is designed for TT-TN network systems, making it an ideal solution for a wide range of applications. Its two-pole design (1+N) allows for effective protection of single-phase circuits with a neutral wire. A key feature of this model is its ability to withstand high current impulses – up to 50kA (Iimp) – which guarantees reliable operation even during strong atmospheric discharges. The VG technology used in this arrester ensures a fast response and minimal response time, protecting connected devices from damage.

Construction and installation for professionals and users

The installation of the DS252VG-300/G arrester is intuitive and does not require specialized knowledge, although it is recommended to entrust this task to a qualified installer. The device is adapted for mounting on a TH35 rail. The solid construction guarantees long-term and trouble-free operation. It is important to select the correct protection for a specific installation, taking into account potential hazards and safety requirements. This arrester not only protects against equipment damage but also minimizes the risk of fire caused by overvoltage.
