Surge arrester T1+T2 8/50 1P 412250

Protection of electrical installations and devices

This type T1+T2 surge protector is a key element in protecting the electrical installation from the effects of sudden voltage surges, e.g. caused by lightning strikes. Applying it in the main distribution board minimizes the risk of damage to connected devices and ensures uninterrupted power supply. This is particularly important in areas prone to frequent storms or in buildings with sensitive electronic equipment.

Functionality and application

The surge protector is designed to work with TN-C, TN-C-S, TT and IT networks, making it a universal solution for various installations. Its construction based on varistor technology ensures a quick and effective response to overvoltages, and the protection level of 1.7 kV guarantees a high degree of safety. Mounting is done on a standard DIN TH-35 mm mounting rail, which simplifies and speeds up installation. The compact size – only 1 module – allows you to save space in the distribution board.

Key features and benefits

• Versatility: compatible with different network systems (TN-C, TN-C-S, TT, IT).
• High efficiency: provides protection against overvoltages with a peak value of up to 20 kA (8/20 µs).
• Optical signaling: an optical indicator informs about the need to replace the surge protector after activation.
• Compact dimensions: occupies only 1 module on the DIN rail, making it easy to install even in tight distribution boards.
• Large wire cross-section: allows connection of wires with a cross-section of up to 35 mm², providing flexibility when selecting power cables.
• Compliance with standards: meets the requirements of IEC/EN 61643-11, guaranteeing safety and reliability.
• Application: ideal for use in main distribution boards as a basic element of protection against overvoltages.

This surge protector is particularly recommended for use in installations requiring a high level of protection against the effects of overvoltages, such as residential buildings, offices, industrial facilities or data centers. It provides not only protection of electrical devices, but also increases the safety of users and minimizes the risk of downtime caused by failures caused by overvoltages.
