Transient Surge Protector Acti9 IPF20 20KA 340V 1P+N

The transient surge protector Acti9 iPF 1P+N 20A 340V 20kA by Schneider Electric is designed to protect electrical installations from transient overvoltages that can occur due to phenomena such as lightning or network switching. This device, part of the Acti9 range, is specifically aimed at residential and commercial applications, offering an effective and safe solution to protect electrical and electronic equipment from unexpected voltage spikes.

The Acti9 iPF K 20 is a type 2 surge arrester, capable of withstanding current discharges of up to 20 kA, in accordance with the IEC 61643-11:2011 standard, making it an excellent choice for installations with a medium risk level of overvoltages. This type of protection is essential in electrical systems where the integrity of electronic equipment and the safety of people depend on continuous and uninterrupted operation.

This limiter is designed to protect 1P+N (one phase and one neutral) electrical installations and is compatible with TT and TN-S earthing systems, which are common in many electrical networks. Its ability to adapt to different earthing systems makes it a versatile and suitable option for a wide variety of installations.

The device has a maximum continuous operating voltage (Uc) of 340 VAC in differential mode between phase and neutral, and 260 VAC between neutral and earth. Regarding its voltage protection level (Up), this limiter offers protection of 1.5 kV in common mode (between neutral and earth) and 1.1 kV in differential mode (between phase and neutral), ensuring effective protection of equipment connected to the grid against voltage spikes.

The Acti9 iPF uses a combination of MOV (Metal Oxide Varistor) and GDT (Gas Discharge Tube) technologies, allowing it to act quickly and efficiently in the event of a detected overvoltage. The MOV limits the voltage peak, and the GDT ensures that residual energy is safely dissipated. This design ensures that overvoltages are efficiently mitigated, protecting both the equipment and the electrical installation as a whole.

The device is easy to install, designed to be mounted on a DIN rail using an adjustable clip system, facilitating its integration into electrical panels or distribution boards. Its compact size, with dimensions of 81 mm in height, 36 mm in width, and 69 mm in depth, allows its installation in confined spaces without compromising functionality or safety. Additionally, its white colour (RAL 9003) ensures that it integrates discreetly into any electrical environment.
