Surge arrester iPRD8-T23-3N 3+1 pole Type2+Type3 8 kA A9L08600

Schneider Electric surge protection for electrical installations

The iPRD8-T23-3N surge arrester is a key element in protecting electrical installations from the effects of surges, both atmospheric (lightning strikes) and grid-related. This Type 2+Type 3 device, designed by Schneider Electric, effectively minimizes the risk of damage to sensitive electronic equipment and ensures uninterrupted power supply. Mounting on a TH-35 mm DIN rail simplifies integration with existing distribution boards.

Functionality and application

This arrester is designed to protect 3-phase circuits with neutral (3P+N) in TN-S and TT network configurations. It provides protection up to 1.2 kV, and its maximum discharge current is 8 kA, making it effective in the event of sudden voltage spikes. Optical indication of the device's status (green/red) allows for quick identification of any failure and the need for replacement. A wire cross-section of up to 35 mm² allows connection of both rigid and flexible wires.

Key features and benefits

• Versatility: The arrester meets the requirements of IEC 61643-1 and EN 61643-11 standards, guaranteeing its compliance with applicable safety standards.
• Fast response: A response time of less than 25 ns provides almost instantaneous protection against surges.
• Visual status control: An optical damage indicator facilitates diagnostics and quick replacement if necessary – saving time and service costs.
• Universal mounting: Mounting on a standard TH-35 mm DIN rail simplifies installation in most distribution boards.
• Robust construction: Short-circuit strength at 50 kA ensures resistance to short-circuit currents occurring during failures.
• Safety: Rated AC voltage of 400V and maximum permissible operating voltage of 350V ensure safe operation of the device under typical electrical installation conditions.
• Protection for various network configurations: Compatible with TN-S and TT systems, increasing its versatility.

The iPRD8-T23-3N surge arrester is a reliable solution for installers looking for effective protection for electrical installations and for end-users who value the safety of their electronic equipment. It provides peace of mind and minimizes the risk of costly failures caused by surges.
