Surge protection device type T2, pole 3+NPE, In: 20kA (8/20), Imax: 40kA, Uc: 255V AC RSP-T2-AC/3+NPE 2617136

Protection of electrical installations against overvoltages

This Type T2 surge protector, designed for AC installations, is a key element ensuring the safety and reliability of the electrical system. Designed to protect against the effects of lightning strikes and voltage surges in the network, it effectively minimizes the risk of damage to sensitive equipment. The 3+NPE design makes it ideal for protecting three-phase installations with a neutral and protective conductor.

Construction and application

This surge protector belongs to class II/B, which means it provides indirect protection against overvoltages. Its task is to discharge excess energy to ground, protecting connected devices from the harmful effects of voltage. It finds application in residential, commercial and industrial buildings - wherever effective protection against overvoltages is required. It is worth remembering that Type T2 surge protectors should be used in conjunction with Type T1 surge protectors, creating a comprehensive protection system.

Key parameters and benefits

• High efficiency: Rated discharge current of 20kA (8/20) and maximum discharge current of 40kA guarantee effective protection even during strong lightning strikes.
• Wide voltage range: Maximum continuous operating voltage of 255V AC allows for use in most standard electrical installations.
• Versatility: 3+NPE design allows protection of both phase, neutral and protective circuits.
• Fast response: Response time of less than 25 ms ensures almost instantaneous reaction to overvoltage, minimizing the risk of damage.
• Safety: The surge protector has a maximum backup of 125A gL/gG, which provides additional safety for the installation.
• Protection level: Surge protectors from the RSP-T2-AC series are characterized by a protection level of Up ≤ 1.5 kV, which translates into a high degree of protection for connected devices.

Installation and selection of the appropriate surge protector should be performed by a qualified electrician in accordance with applicable standards and regulations. A properly selected and installed surge protector is an investment in the safety and long-term reliability of the electrical installation.
