Quick PRD20r 3P+N Transient Surge Protector

The Quick PRD20r 3P+N transient surge protector from Schneider Electric, reference A9L1629, is designed to protect residential and commercial building electrical installations from transient overvoltages caused by atmospheric events or disturbances in the power grid. This Type 2 device is recommended for main distribution boards with a moderate level of risk, providing a reliable and efficient solution for protecting electronic equipment and sensitive circuits.

This surge protector features an integrated automatic switch that acts as a safety disconnector, ensuring the device automatically deactivates at the end of its service life, eliminating the risk of overheating or malfunction. Its integrated breaking capacity is 25 kA, ensuring robust protection against even the most severe overvoltages.

The Quick PRD20r has a maximum discharge current (Imax) of 20 kA and a nominal discharge current (In) of 5 kA, enabling it to easily handle transient overvoltages that may occur in an electrical installation. Additionally, this device is compatible with TT and TN-S earthing systems, offering great versatility in its application.

One of the standout features of this model is the remote signalling, which allows for monitoring the status of the surge protector and alerts users when cartridges need to be replaced. This function is particularly useful in installations where access to the electrical panel may be limited or where continuous monitoring is required.
