Surge protective device iPRD65r-T2-3N 3+1-conductor Type2 65 kA with contact A9L65601

Protection of electrical installations against overvoltage

The iPRD65r-T2-3N surge arrester is a reliable device used to protect electrical installations from the effects of atmospheric and switching surges. Designed for mounting on a TH-35 mm DIN rail, it provides comprehensive protection in TN-S and TT network systems. Its 3+1 pole design ensures protection of both phases and the neutral conductor, which is crucial for the safety of the entire system.

Functionality and application

The Class T2 device, with a protection level of 1.5 kV, effectively limits the voltage to a safe level, protecting connected devices from damage. The rated discharge current of 65 kA (8/20) guarantees high resistance to strong surge pulses. This arrester is used in residential, commercial and industrial buildings, where protection against overvoltage is particularly important – e.g. in main and sub-distribution boards. Additionally, the presence of a remote signaling contact allows for quick identification of device operation and taking appropriate repair actions.

Construction features and advantages

The arrester design takes up 4 modules, making it easy to install even in tight distribution boards. The ability to connect wires with a cross-section of up to 35 mm² (both solid and stranded) ensures compatibility with various types of installations. Optical signaling of operation facilitates diagnostics and allows for quick problem localization. Short-circuit withstand strength (Isccr) at 50 kA ensures stable operation of the device in the event of a short circuit in the installation. Using the iPRD65r-T2-3N surge arrester is an investment in the safety and reliability of the electrical system – it minimizes the risk of equipment failure and downtime.
