Surge protective device iPFK40-T2-3N 3+1-pole Type2 40 kA A9L15688

Protection of electrical installations with surge protectors Schneider Electric

The iPFK40-T2-3N surge protector is a key element in protecting electrical installations from the effects of lightning strikes and overvoltages originating from the grid. This Type 2 device, with a surge current of 40 kA, effectively protects against damage to electrical and electronic equipment, minimizing the risk of failures and downtime. This is particularly important in residential, commercial and industrial buildings where sensitive devices are exposed to interference.

This surge protector is designed for mounting on a TH-35 mm DIN rail and occupies 4 modules. This makes it easy to integrate into an existing electrical distribution board. Optical signaling indicates any damage after the surge protector has operated, making quick identification and replacement easier.

Versatility and compatibility

The design of the surge protector allows it to be used in various network configurations – TN-S and TT. This makes it a universal solution for a wide range of installations. Short-circuit strength at 25 kA provides additional safety in the event of a short circuit in the installation. The maximum wire cross-section of up to 25 mm² (solid/stranded) and 16 mm² (flexible) allows connection of wires of different thicknesses, adapting to the specifics of the installation.

The surge protector has a protection level of 1.5 kV for both L-N and N-PE paths, ensuring effective protection against overvoltages. In combination with appropriate overcurrent protection (up to 40 A), it provides a comprehensive solution for protecting the electrical installation. It is important to remember that regular inspection of the surge protector's condition and its replacement after operation are crucial to ensure continuous protection.
