Surge arrester type T1+T2, 2-pole, 230V AC, Iimp: 25kA (10/350), Imax: 100kA RSP-E25-11 2617364

Surge protection in AC installations

This two-pole surge limiter, designed for 230V AC installations, is a key element ensuring the safety and reliability of the electrical system. Class I+II (T1+T2) construction means it effectively protects against both direct and indirect effects of lightning strikes and overvoltages of atmospheric or network origin. This is an ideal solution for both installers and end-users looking for comprehensive protection.

This limiter is distinguished by its high strength parameters. The peak current Iimp on the L-N line is 25kA (10/350), and the maximum discharge current Imax is as high as 100kA. In addition, the protection of the N-PE line is equally effective – the peak current reaches 50kA (10/350), and the maximum discharge current is also 100kA. This specification guarantees effective protection even in the event of strong disturbances. MOV varistor protection for L-N and GDT for N-PE ensures optimal response to various types of overvoltages.

• Versatile application: The limiter works perfectly in main distribution boards (MB) in TT, TN-S and TN-C networks.
• Status indication: Equipped with a potential-free contact, it enables remote failure signaling, allowing for a quick response and minimizing downtime.
• Compact dimensions: A width of 36mm per pole makes installation easier even in crowded switchboards.
• Compliance with standards: Meets the requirements of IEC/EN 61643-11:2011, IEC 60364-4-53 and IEC 62305 standards, which confirms its high quality and safety of use.
• Modular replaceable design: Enables quick and easy replacement of the damaged element without the need to disassemble the entire switchboard.

This limiter is an investment in the safety and long-term reliability of the electrical installation. Thanks to its high technical parameters and compliance with applicable standards, it provides solid protection against the effects of overvoltages, minimizing the risk of failures and costly repairs.
