Surge protector T2 20 KA 2P 412221

Surge protection for your installation

This two-pole T2 surge protector from Legrand's ON300 series is a key element ensuring electrical safety in residential and commercial buildings. The device effectively protects sensitive electronic equipment from the effects of lightning strikes and overvoltages in the power grid. Designed to work with TN, TNC, TN-S and TN-C-S installations, it offers universal application and easy mounting on a standard 35mm DIN rail.

Functionality and application

This arrester is type 2 (formerly class C), which means it is intended for installation in secondary circuits, after a type 1 arrester (installed in the main connection). Its task is to dissipate surge energy, minimizing the risk of damage to connected devices. Thanks to this, you can sleep peacefully knowing that your installation is protected against sudden voltage spikes. The optical indication of the device's status informs about the need to replace the insert after activation.

Key features and benefits

• Versatility: Compatible with various network systems – TN, TNC, TN-S, TN-C-S.
• Effective protection: Rated discharge current of 5 kA provides protection against most overvoltages. Maximum peak surge current is as high as 20kA.
• Easy installation: Mounting on a standard 35mm DIN rail – saves time and installation costs.
• Status indicator: Optical indication of insert status facilitates control and replacement.
• Compact dimensions: Occupies only 2 modules – ideal for switchboards with limited space.
• Safety: Compliance with IEC/EN 61643-11 standard guarantees high quality and reliability.
• Leads: Possibility of connecting wires with a cross-section of up to 35 mm² (rigid) or 25 mm² (flexible).
• Operating voltage: Adapted to operate in 230V AC networks with a maximum continuous voltage of 320V AC.

This arrester is an investment in the safety of your equipment and peace of mind. It provides reliable protection against the effects of overvoltages, minimizing the risk of failures and costly repairs.
