Surge arrester KSD-T2 275/40 M KANLUX IDEAL TS 23131

Power supply protection – surge arrester KSD-T2 275/40

This varistor surge arrester class 2 (T2/C) is a key element in protecting electrical installations from the effects of overvoltage. It is suitable for both buildings without a lightning protection system and those with a cable line connection, where it provides sufficient protection, eliminating the need to use class 1 arresters (T1/B). The device is designed to protect against induced and switching surges that can damage sensitive electrical equipment.

The KSD-T2 arrester is designed in accordance with the PN-EN61643-1 standard, which guarantees its reliability and effectiveness. It is made of high-quality components and manufactured in the European Union. It provides protection within zone 1-2 according to EN62305.

Key features:

• Rated voltage is 230V AC, making it suitable for standard electrical installations.
• Maximum discharge current (Imax) at 40kA provides high capacity to dissipate energy during surges.
• Rated discharge current (In) is 20kA, which determines the ability to withstand discharge currents multiple times.
• Protection level voltage (Up) ≤1.3kV effectively limits the voltage to a safe level.
• Transient surge current (Itrans) is 40kA, which is an important parameter determining resistance to sudden current surges.
• Residual current parameters (Ipe) are 30µA, minimizing the impact on the operation of RCD devices.
• Compact dimensions – occupies only 1 module – facilitate installation in the switchgear cabinet.
• Wide operating temperature range from -40°C to +70°C enables use in various environmental conditions.
• IP 20 degree provides protection against finger contact and is intended for indoor mounting.

The KSD-T2 arrester has a connection terminal block, which facilitates and speeds up its installation. Its versatility makes it an ideal solution for both professional installers and end-users who care about the safety of their electrical appliances. Thanks to its solid construction and compliance with European standards, it provides long-lasting and reliable protection against the effects of overvoltage. The manufacturer's warranty is 5 years.
