T2 surge arrester 20 kA 412297

Surge protection for your installation

This Type T2 surge limiter insert is a key element in protecting the electrical installation from the effects of sudden voltage spikes, both from the grid and caused by atmospheric discharges. Using this type of insert minimizes the risk of damage to connected devices and ensures uninterrupted power supply. This is especially important in places exposed to frequent voltage changes or in buildings without dedicated lightning protection.

The insert is designed for mounting on a standard DIN TH-35 mm mounting rail, which facilitates its installation and replacement. The compact size – only 1 module – allows you to save space in the switchgear. Optical signaling informs about the possible operation of the limiter, which allows for a quick response and assessment of the protection status.

Application and benefits:

• Protection of sensitive devices: Protects electronic equipment such as televisions, computers, alarm systems and home automation against damage caused by overvoltages.
• Compliance with standards: Ensures compliance with applicable electrical safety standards, which is important for installations subject to technical supervision.
• Easy replacement: The insert allows for quick replacement of a damaged element without the need to disassemble the entire limiter. This translates to minimal system downtime.
• Versatility: Can be used in various network configurations: TN, TN-C, TN-C-S and TT.
• High efficiency: Rated discharge current of 5 kA (peak value 8/20 µs) and protection level of 1.2 kV (L-N) guarantee effective protection against overvoltages. It also offers a protection level of N-PE at 1.5kV.

This limiter is compatible with the Legrand ON300 series, ensuring easy integration with other elements of this manufacturer's surge protection system. This allows you to create a comprehensive solution tailored to the individual needs of each electrical installation. Remember to properly ground or connect to the PE protective conductor to ensure the full functionality of the device.
