Surge arrester KSD-T2 275/160 3P+N 23133

Electrical installation protection with surge limiters KSD-T2

The KSD-T2 275/160 3P+N surge limiter is a key element in protecting electrical installations from the effects of overvoltages, both induced by lightning strikes and switching surges. It is a Class 2 (Type 2/C) device, designed to protect buildings without a lightning protection system or with a cable connection. In such situations, this limiter provides sufficient protection, eliminating the need for additional Class 1 limiters.

This three-phase limiter (3P+N) is ideal for protecting circuits in residential, commercial and industrial buildings. Its varistor-based design guarantees a quick and effective response to sudden voltage increases, protecting connected devices from damage. Mounting is done on a standard TH35 rail, which facilitates integration with existing electrical infrastructure.

Key features and benefits:

• Versatile application: The KSD-T2 limiter works well in both new and modernized installations.
• Effective protection: Provides protection against induced and switching surges, minimizing the risk of failures and downtime.
• Simple installation: Mounting on a TH35 rail makes installation easier and faster.
• Compliance with standards: The device meets the requirements of PN-EN61643-1 standard, which guarantees its safety and reliability.
• High impulse withstand current: Maximum discharge current Imax at 40kA provides effective protection even with strong overvoltages.
• Low residual current: The I(pe) parameter of 30µA minimizes the impact of the limiter on the operation of other devices in the installation.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to 70°C makes the limiter suitable for use in various environmental conditions.

KSD limiters are manufactured in the European Union, which confirms their high quality of workmanship and compliance with European safety standards. By choosing this product, you are investing in reliable protection of your electrical installation and peace of mind for the safety of connected devices. Thanks to its compact size (4 modules) it does not take up much space in the switchboard. The protection level voltage U(p) ≤1.3kV ensures effective voltage reduction during overvoltages.
