Surge arrester type T2+T3, pole 1+NPE, In: 10kA (8/20), Imax: 20kA, Uc: 255-385V RSP-T2T3-AC/1+NPE 2617141

Protection of electrical installations against overvoltage

This type T2+T3 surge protector is a key element in protecting electrical installations in residential and commercial buildings. It provides effective protection against the effects of lightning strikes and surges, minimizing the risk of damage to electrical and electronic devices. The 1+NPE construction makes it ideal for protecting single-phase circuits with neutral and protective conductors.

Characteristics and application

This surge protector combines the features of type T2 and T3 surge protectors, offering versatile protection. Type T2 protects against direct lightning strikes and indirect effects of discharges, while type T3 provides additional protection against residual overvoltages. This makes the device perfect for installations where a high level of protection is required. Use in lightning protection systems (LPZ 0-1 zone concept) allows for optimal protection of sensitive devices.

Key features and benefits

• High efficiency: Rated discharge current of 10kA (8/20) and maximum discharge current of 20kA guarantee effective protection even with strong surges.
• Wide voltage range: Maximum continuous operating voltage Uc in the range of 255-385V allows use in various electrical installations.
• Fast response time: Response time of less than 25ns ensures almost instantaneous reaction to overvoltages, minimizing the exposure time of devices to harmful effects.
• Low protection level: Protection level ≤1.5kV provides a high degree of safety for connected devices.
• 1+NPE construction: Allows protection of the entire circuit in one device, simplifying installation and reducing costs.
• Compliance with standards: The surge protector is designed in accordance with IEC 61643-11:2011, which confirms its high quality and reliability.

Installation and safety

The installation of the surge protector should be carried out by a qualified electrician, in accordance with applicable regulations and standards. Proper installation guarantees optimal protection efficiency and safety of use. Remember to select appropriate overcurrent protection (maximum backup: 125A gL/gG) to ensure full protection of the installation.
