Surge arrester type T1+T2, 3-pole, 230V AC, Iimp: 25kA (10/350), Imax: 100kA RSP-E25-30 2617365

Electrical installation protection – reliability and safety

This three-pole surge protector, designed for operation in 230V AC networks, is a key element ensuring protection against the effects of lightning strikes and overvoltages in the installation. Class I+II (T1+T2) construction means it effectively eliminates both direct lightning strikes and overvoltages passing from the network. This is an ideal solution for main distribution boards in residential, commercial and industrial buildings.

Construction and application

The surge protector utilizes MOV (Metal Oxide Varistor) technology in combination with a potential-free contact, which enables remote signaling of the device's status. In the event of a failure, the contact changes state, informing about the need to replace the surge protector. A width of 36mm per pole allows for easy installation in standard distribution boards. Peak current Iimp at 25kA (10/350) and maximum discharge current Imax 100kA guarantee effective protection even with strong voltage impulses. The surge protector is adapted to work in three-phase 3+0 networks with a voltage of 275VAC.

Key features and benefits

• Versatile protection: Class I+II (T1+T2) provides comprehensive protection against overvoltages from various sources.
• Status signaling: Potential-free contact enables remote monitoring of the surge protector's status and quick reaction in case of failure.
• High efficiency: Peak current of 25kA and maximum discharge current of 100kA guarantee effective protection of the electrical installation.
• Easy installation: Modular design and width of 36mm per pole facilitate mounting in standard distribution boards.
• Compliance with standards: Meets the requirements of IEC/EN 61643-11:2011, IEC 60364-4-53 and IEC 62305 standards, ensuring safety and reliable operation.
• Network versatility: Designed for TT, TN-S and TN-C networks, making it a universal solution for most installations.

The maximum continuous operating voltage is 275 V AC, the rated discharge current (8/20 μs) is 25 kA, and the maximum discharge current (8/20 μs) Imax reaches 100 kA. The protection level U is 1.2 kV and the response time is less than or equal to 25 Ns.

This surge protector is an investment in the safety of your electrical installation and devices connected to the network. It provides effective protection against overvoltages, minimizing the risk of damage and downtime. This is especially important in areas prone to frequent storms or with an unstable power grid.
