Surge arrester KSD-T1+T2 275/180 3P KANLUX IDEAL TS 23921

Surge protection for your installation

The Kanlux KSD-T1+T2 275/180 3P surge arrester is a key element in protecting the electrical installation from the effects of lightning strikes and induced and switching surges. The device is designed for use in TN/TT networks, providing comprehensive protection for both residential and commercial buildings. Mounting on a TH35 rail simplifies integration with the existing distribution board.

Construction and application

This arrester combines the features of a Type 1 (T1) and Type 2 (T2) arrester, offering a double layer of protection. Class B+C means the device effectively suppresses both lightning strikes and smaller, but more frequent surges. Use inside the building guarantees optimal protection of sensitive electronic devices. Compliance with EN61643-1 and EN61643-11 standards confirms its high quality and reliability. KSD arresters are manufactured in the European Union, which demonstrates compliance with strict quality standards.

Key parameters and benefits

• Peak surge current (Imax): 60kA – provides effective protection even with strong surges.
• Rated voltage: 230V AC – ideal for standard electrical installations.
• Protection level (Up): ≤1.5kV – minimizes the risk of damage to connected devices.
• Residual current (Ipe): 30µA – low residual current ensures minimal impact on the operation of protected circuits.
• Number of poles: 3P – designed for three-phase installations, providing full protection of the entire system.
• Operating temperature: -40°C to +70°C – possibility of use in a wide range of ambient temperatures.
• Protection degree IP20: Indicates protection against touching with a finger, which is important for safety.
• Rated discharge current (In): 30kA - determines the ability to dissipate energy during lightning strikes.

The KSD-T1+T2 arrester is an investment in the safety and long-term efficiency of the electrical installation, protecting against costly failures and downtime caused by surges. Thanks to its solid construction and compliance with standards, it is a reliable solution for demanding users and professionals.
