Surge protective device iPRD8r-T23-1N 1+1-pole Type2+Type3 8 kA with contact A9L08501

Electrical installation protection with surge limiters Schneider Electric

The iPRD8r-T23-1N surge limiter is a reliable element protecting electrical installations from the effects of current surges and overvoltages. Designed for mounting on a TH-35 mm DIN rail, it is a key component in overvoltage protection systems, ensuring the safety of devices and installations. This model combines the functions of type 2 and 3 limiters, offering comprehensive protection in one device.

Construction and application

This limiter is single-pole, designed to operate in TN-S and TT networks. Its compact size – only 2 modules – makes it easy to install even in crowded distribution boards. The built-in remote signaling contact allows for quick detection of the limiter's operation, which is particularly important in monitoring and remote control systems. Optical indication of operation on the device further facilitates problem identification. Designed to protect against differential and common mode overvoltages, it effectively protects against damage caused by lightning strikes or network disturbances.

Key features and benefits

• Versatility: The combination of types 2 and 3 in one device minimizes the need to use multiple protective elements, simplifying the design and installation of installations.
• High efficiency: Rated discharge current of 8 kA and short-circuit strength of 50 kA guarantee effective protection even with strong overvoltages.
• Status signaling: Built-in remote signaling contact and optical indication of operation facilitate diagnostics and rapid response in the event of a failure.
• Universality: The possibility of use in TN-S and TT network systems provides a wide range of applications – from home installations to industrial facilities.
• Safety: L-N protection level of 1.1 kV and L-PE/N-PE of 1.4 kV provides a high degree of protection against equipment damage.
• Installation flexibility: The possibility of connecting wires with a cross-section of up to 35 mm² (rigid and flexible) ensures compatibility with various types of installations.
• Solid construction: Made of high-quality materials, ensures long-lasting and reliable operation of the device (IP20).

This limiter is an ideal solution for both professional installers and end-users looking for reliable protection of their electrical equipment. It provides peace of mind by minimizing the risk of damage caused by overvoltages.
