Surge arrester iPRD1 12.5R-T12-1N 2-pole Type 1+2 (class B+C) A9L16282

Electrical installation protection with surge arrestors iPRD1

The iPRD1 12.5R-T12-1N surge arrester is a reliable device used to protect electrical installations from the effects of surges, both atmospheric (lightning strikes) and switching. It is a key element ensuring the safety of equipment and the continuity of power supply in residential, commercial and industrial buildings. The design based on spark gap-varistor technology guarantees a fast response and effective suppression of interference.

This 2-pole arrester of Type 1+2 (B+C) class is perfect for TN-S, TT and TN installations, offering versatility of application. The integrated signaling contact informs about the operation of the device, which facilitates diagnostics and a quick response in the event of a surge. The ability to rotate the base by 180 degrees simplifies installation in tight spaces.

Key features and benefits

• High protection efficiency: Surge current of 12.5 kA per pole provides effective protection against strong surges.
• Versatility: Compatible with various network systems (TN-S, TT, TN), which increases its applicability.
• Status signaling: Built-in signaling contact facilitates monitoring of the device status and quick identification of problems.
• Easy installation: The ability to rotate the base by 180 degrees makes installation easier even in difficult conditions.
• Safety: Compliance with standards ensures a high level of safety.
• Solid construction: Made of high-quality materials, guarantees long life and reliable operation.
• Wire cross-section: Supports wires with a cross-section of up to 35 mm² (rigid) and 25 mm² (flexible) ensures compatibility with most installations.
• Compact dimensions: Occupies only 4 modules on a TH-35 mm DIN rail, saving valuable space in the distribution board.

Application and installation

The iPRD1 arrester is used wherever protection against surges is required – in apartments, offices, industrial buildings and public facilities. Installation is on a standard TH-35 mm DIN rail, making it easy to install for both professionals and experienced DIY enthusiasts. Remember to select the correct preliminary protection (e.g. overcurrent circuit breaker) and to properly ground the installation. The L-N/N-PE protection level is 1.5 kV, which provides a high degree of protection against damage to sensitive electronic devices.
