Surge protective device iPRD20-T2-1 1-pole Type2 20 kA A9L20100

Protection of electrical installations with surge limiters Schneider Electric

The iPRD20-T2-1 surge limiter is a key element in protecting electrical installations from the effects of surges, which can damage sensitive equipment. The device is designed for protection in TN-C and TT networks, providing effective protection in both residential and commercial buildings. Its compact size – only 1 module – allows for easy mounting on a TH-35 mm DIN rail, saving valuable space in the distribution board.

Functionality and application

This limiter, classified as Type 2, effectively suppresses transient surges that occur, for example, during thunderstorms or as a result of switching on large inductive loads. The rated discharge current of 20 kA guarantees high resistance to sudden voltage spikes. Optical signaling informs about the operation of the device, which facilitates troubleshooting and rapid response. This is particularly important for installers who can effectively monitor the status of the protection in this way.

Specification and design features

The device is characterized by high quality and durability. The maximum wire cross-section of 35 mm² allows connection of a wide range of wires, both rigid and flexible. The protection level of 1.1 kV provides effective protection against damage caused by surges. The short-circuit withstand strength (Isccr) of 50 kA testifies to the solid construction and ability to withstand extreme operating conditions. The use of characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. It protects the circuit against overload and short circuit - like most circuit breakers in this class.

• Mounting: Easy mounting on TH-35 mm DIN rail – a standard solution that facilitates installation and replacement of the device.
• Signaling: Optical indication of operation – quick identification of the device status without the need for disassembly.
• Wire cross-section: Supports wires up to 35 mm² – compatibility with various types of electrical installations.
• Application: Ideal for protecting distribution networks in residential, commercial and industrial buildings.
• Network systems: Compatible with TN-C and TT network systems - a wide range of applications in various electrical installation configurations.
• Protection class: IP20 - protection against touching with a finger and solid objects larger than 12.5 mm - standard protection for devices mounted inside electrical distribution boards.
