Surge protective device iPRD20r-T2-3N 3+1-conductor Type2 20 kA with contact A9L20601

Schneider Electric surge protectors

The iPRD20r-T2-3N surge protector is a key element in protecting electrical installations in residential and commercial buildings. The device effectively protects against the effects of overvoltages that can damage sensitive electronic and electrical equipment. This is particularly important in areas prone to frequent lightning strikes or in installations powering highly sensitive devices.

This three-pole (3P+N) Class T2 surge protector, with a maximum energy discharge capacity of 20 kA, provides comprehensive protection against overvoltages from the power grid and those caused by indirect lightning strikes. The built-in remote signaling contact allows continuous monitoring of the device's status and informs of any activation - which is extremely important for rapid response and minimizing potential losses.

Design features and application

The surge protector is designed for mounting on a standard 35 mm DIN rail and occupies 4 modules, making it easy to integrate into an existing electrical distribution board. It is compatible with TN-S and TT network systems, making it a universal solution for different types of installations. Made of high-quality materials, it guarantees reliable operation and long service life.

Thanks to the use of MOV + GDT technology (varistor + GDT), the surge protector is characterized by high efficiency in suppressing overvoltages and resistance to multiple current pulses. The maximum wire cross-section of up to 25 mm² (solid/stranded) and 16 mm² (flexible) ensures easy connection to the existing electrical infrastructure. The surge protector has optical indication of the operating status, which facilitates visual control of its efficiency.
