Surge arrester type T1+T2, 4 poles, Limp: 7 kA (10/350), In: 20kA (8/20), Imax: 50kA, Uc: 275V AC RSP-T1T2-AC 7/4P 2617128

Protection of electrical installations against overvoltage

This four-pole surge protector type T1+T2 is a key element in protecting electrical installations in residential and industrial buildings. It provides comprehensive protection against the effects of lightning strikes and overvoltages from the grid. Its design combines the advantages of type T1 and T2 surge protectors, offering a fast and effective response to sudden voltage changes.

This surge protector is designed to work with AC installations with a voltage of 275V AC. Its task is to minimize the risk of damage to connected electrical devices, such as RTV equipment, household appliances, automation systems or lighting. Thanks to its high withstand current parameters, it effectively protects circuits against overloads and short circuits - like most circuit breakers in this class.

Key features and applications:

• Versatility: ideal for use in AC installations, providing protection against overvoltages of both atmospheric and grid origin.

• Two-stage protection: the combination of class T1 and T2 ensures a fast response to strong impulses (T1) and precise protection against smaller, but more frequent overvoltages (T2).

• High efficiency: peak current Limp at 7 kA (10/350 μs) and rated discharge current In 20 kA (8/20 μs) guarantee effective protection even in the event of strong discharges.

• Solid construction: maximum discharge current Imax of 50 kA demonstrates the high durability of the device and its ability to absorb surge energy.

• Compliance with standards: designed in accordance with IEC 61643-11:2011, which confirms its safety and reliability.

This surge protector finds application in residential buildings, commercial facilities and industrial plants - wherever there is a need to protect sensitive electrical equipment from the effects of overvoltage. Installation in places exposed to direct lightning strikes or near sources of electromagnetic interference increases the effectiveness of protection. This is particularly important in areas with high thunderstorm activity.
