Surge arrester type T2+T3, 2 poles, In: 10kA (8/20), Imax: 20kA, Uc: 275-385V RSP-T2T3-AC/2P 2617138

Protection of electrical installations against overvoltage

This two-pole surge protector from the RSP-T2T3-AC series is a key element ensuring the safety and reliability of the electrical installation. Designed to protect low-voltage devices against the effects of lightning strikes and overvoltages, it is an integral part of lightning protection systems in LPZ 0-1 zones. Its design based on varistor-spark gap technology guarantees a quick and effective response to sudden voltage increases.

Characteristics and application

This surge protector combines the functions of type T2 and T3 limiters, which means it provides protection against both direct and indirect effects of lightning strikes. The rated discharge current of 10kA (8/20) and the maximum discharge current of 20kA (8/20) demonstrate its high efficiency. The continuous operating voltage in the range of 275-385V AC makes it compatible with most standard electrical installations. The fast response time, not exceeding 25ns, minimizes the risk of damage to connected devices.

Key advantages for the installer and user

• Versatility: The combination of class T2 and T3 in one device simplifies the design of surge protection systems.
• High efficiency: Rated discharge current of 10kA and maximum discharge current of 20kA provide solid protection against overvoltages.
• Fast response: Response time below 25ns minimizes the exposure time of devices to harmful overvoltage effects.
• Safety: Protection level ≤1.5kV effectively limits the voltage to a safe level.
• Compliance with standards: The device meets the requirements of IEC 61643-11:2011, which guarantees its quality and reliability.
