Surge arrester type T1+T2, 1 pole, 230V AC, Iimp: 25kA (10/350), Imax: 100kA RSP-E25-10 2617363

Protection of electrical installations against overvoltage

This Type I+II (T1+T2) single-pole surge protector is a key element in protecting electrical installations from the effects of sudden voltage surges, including lightning strikes. Designed to operate in 230V AC networks, it provides comprehensive protection for both residential and commercial installations. The plug-in design simplifies installation and replacement, and the compact dimensions (36mm wide per pole) allow installation even in crowded distribution boards.

Functionality and application

This surge protector effectively protects against overvoltages in both L-N and N-PE lines. Thanks to the use of single-pole MOV (Metal Oxide Varistor) technology with an additional potential-free contact, it enables remote signaling of damage to a single-phase network – which is particularly important in monitoring and automation systems. It is ideal for use in main distribution boards (MD) in TT, TN-S and TN-C networks. Compliance with IEC/EN 61643-11:2011, IEC 60364-4-53 and IEC 62305 standards guarantees its reliability and safety.

Parameters and performance

The surge protector is characterized by high strength parameters. The peak current Iimp is 25kA (10/350), and the maximum discharge current Imax is as high as 100kA. The rated discharge current is 25kA, which ensures effective protection against overloads. The surge protector's response time is very short – less than 25 nanoseconds, minimizing the risk of damage to connected devices. The maximum continuous operating voltage U is 275 V AC. A built-in mechanical status indicator (green/red flag) allows for a quick visual assessment of the device's condition after a surge event.
