T2 surge arrester 40 KA 412299

Surge protection for your installation

This T2 surge arrester insert, with a current of 40kA, is a key element in protecting the electrical installation from the effects of sudden voltage surges. It provides protection for both devices sensitive to overvoltage and the entire electrical network in the building. This is particularly important in areas prone to storms or with an unstable power grid.

Functionality and application

The T2 arrester insert is designed to work with overcurrent circuit breakers and acts as the second stage of protection in a surge protection system. This means that it absorbs part of the surge energy that has passed through the first stage of protection (e.g., a T1 arrester), thereby protecting the devices connected to the installation. This minimizes the risk of damage to electronic equipment, as well as fires caused by short circuits. Installation is done on a standard DIN TH-35 mm mounting rail, which facilitates integration with the existing distribution board.

Key features and benefits

• High efficiency: Rated discharge current of 20kA (peak value) and the ability to extinguish pulses with a current of 40kA guarantee effective protection against surges.
• Versatility: Designed to work in various network configurations – TT, TN-C, TN-C-S and TN – making it compatible with most electrical installations.
• Fast signaling: Optical status indicator allows for easy assessment of whether the insert needs to be replaced after the arrester has operated. Green indicates efficiency, and orange – the need for replacement.
• Compact dimensions: Occupies only 1 module on the DIN rail, which saves space in the distribution board.
• Safety: Compliance with IEC/EN 61643-11 standard ensures a high level of safety and reliability.
• Protection for sensitive devices: Protects against damage to electronic equipment such as computers, televisions and alarm systems.
• Durable construction: Made of high-quality materials ensuring long-lasting and reliable operation.
• Low AC residual voltage: 320V ensures compatibility with most power grids.

This arrester is an ideal solution for both electrical installers looking for reliable protection for their customers, and for end-users who want to protect their electronic equipment from the effects of surges.
