Surge arrester type T2+T3, 1 pole, In: 10kA (8/20), Imax: 20kA, Uc: 275-385V RSP-T2T3-AC/1P 2617137

Protection of electrical installations and devices

This single-pole surge protector type T2+T3 is a key element ensuring safety in electrical installations. It is designed to protect against the effects of lightning strikes and surges that can damage sensitive equipment. Its versatility makes it suitable for both new and modernized installations.

How it works and where to use?

This surge protector combines the features of T2 and T3 protection, meaning it effectively suppresses both strong voltage impulses (T2) and residual overvoltages (T3). It is ideal for use in places where high protection efficiency and a fast response time are required. Application in the protection zone concept LPZ 0-1 allows for comprehensive building protection.

Key features and benefits

• High energy absorption capacity: Rated discharge current at 10kA (8/20) and maximum discharge current of 20kA guarantee effective protection even with strong surges.
• Fast response time: Response time of less than 25ns minimizes the risk of damage to connected devices. This means the surge protector reacts almost instantly to the appearance of dangerous voltage.
• Wide operating voltage range: Maximum continuous operating voltage Uc in the range of 275-385V ensures compatibility with most standard AC installations.
• Low protection level: Protection level ≤1.5kV effectively limits surges to a safe level.
• Compact size: Single-pole design simplifies installation and saves space in the distribution board.
• Compliance with standards: The surge protector is designed in accordance with IEC 61643-11:2011, which confirms its quality and safety of use.

This surge protector is designed to work with fuses with a maximum value of 125A gL/gG, which further increases the safety of the installation. Thanks to this, it constitutes a reliable protective barrier for your electrical devices.
