Surge arrester type T1+T2, 3-pole, Limp: 12.5 kA (10/350), In: 30kA (8/20), Imax: 60kA, Uc: 275V AC RSP-T1T2-AC 12.5/3P 2617121

Protection of installations against overvoltages – reliability and safety

This three-pole surge arrester type T1+T2 is a key element ensuring the protection of electrical installations against the effects of lightning strikes and fast voltage transients. Designed to operate in AC networks, it effectively minimizes the risk of damage to sensitive equipment and ensures uninterrupted power supply. Its construction combines the features of type T1 and T2 arresters, which means it can cope with both direct lightning strikes and induced overvoltages.

Construction and application

This arrester is intended for mounting in electrical distribution boards, constituting the first line of defense against overvoltages. Its task is to discharge excess energy to ground, protecting connected devices from damage. The peak current Limp at 12.5 kA (10/350) means that it can withstand even strong current pulses, and the rated discharge current In of 30 kA (8/20) guarantees effective protection in the event of frequent overvoltages. The maximum discharge current Imax at 60 kA confirms its resistance in extreme conditions. The operating voltage Uc 275V AC makes it compatible with most standard installations.

Key features and benefits

• Versatile protection: the combination of class T1 and T2 provides comprehensive protection against various types of overvoltages.
• High efficiency: Limp, In and Imax currents guarantee effective discharge of surge energy.
• Durability and reliability: solid construction ensures long-term, trouble-free operation.
• Universality: ideal for use in residential, commercial and industrial buildings.
• Easy installation: designed for quick and easy installation in standard electrical distribution boards.
• Safety: protects electrical devices from damage caused by overvoltages, minimizing the risk of fire or failure.

Thanks to this surge arrester, you can be sure that your electrical installation is properly protected against the effects of unforeseen weather events and disturbances in the power grid. It is an investment in the safety and continuity of operation of your devices.
