Surge arrester type T1+T2, 2-pole, Limp: 7 kA (10/350), In: 20kA (8/20), Imax: 50kA, Uc: 275V AC RSP-T1T2-AC 7/2P 2617126

Protection of electrical installations and devices

This two-pole surge protector from the RSP-T1T2-AC 7 series is a key element ensuring the safety of the electrical installation and the devices connected to it. Designed to protect against the effects of lightning strikes and overvoltages, it is a reliable barrier against potential damage. Its construction based on a combination of a varistor and a spark gap guarantees a quick and effective response to sudden voltage changes.

Construction and application

This surge protector combines the functions of two types of protection – T1 and T2. Type T1 provides protection against direct lightning strikes, and type T2 protects against overvoltages resulting from indirect discharges or network maneuvers. Thanks to this, one device provides comprehensive protection. It is ideal for use in installations with a voltage of 275V AC, both in residential and commercial buildings. It can be mounted in accordance with the concept of lightning protection zones (LPZ 0-1), which increases the efficiency of the entire surge protection system.

Key features and benefits

• High efficiency: Peak current Limp at 7 kA (10/350 μs) and rated discharge current In of 20 kA (8/20 μs) guarantee effective protection against overvoltages with high energy.
• Wide range of protection: Maximum discharge current Imax of 50 kA allows absorption of even very strong voltage pulses.
• Versatility: Two-pole construction makes the surge protector easy to install and can be used in various electrical network configurations.
• Compliance with standards: The device has been designed in accordance with IEC 61643-11:2011, which confirms its quality and safety of use.
• Reliability: Resistance to repetitive impulses and high quality of workmanship ensure long-lasting and trouble-free operation of the device.
• Reduced risk of damage: By protecting electrical devices from overvoltages, the surge protector minimizes the risk of costly repairs or equipment replacement.
• Safety: Provides protection for people in the building from electric shock caused by overvoltages.
