Surge arrester KSD-T1+T2 275/240 3P+N KANLUX IDEAL TS 23920

Surge Protection – Reliability and Installation Safety

The KSD-T1+T2 275/240 3P+N surge arrester is a key element of the surge protection system, designed to protect electrical installations from the effects of lightning strikes and induced and switching surges. This device, manufactured in accordance with EN61643-1 and EN61643-11 standards, provides comprehensive protection in TN/TT networks, minimizing the risk of equipment damage and failures. This is particularly important in residential, commercial and industrial buildings where stable power supply is essential for the proper functioning of devices.

Construction and principle of operation

The KSD-T1+T2 arrester combines the features of a type 1 (class B) and type 2 (class C) arrester, which means it effectively responds to both direct and indirect lightning strikes. This provides multi-stage protection, protecting sensitive electronic devices from sudden voltage spikes. The construction based on varistors allows for quick dissipation of surge energy to ground, minimizing its impact on the protected installation. Mounting is done on a standard TH35 rail, which facilitates integration with the existing electrical system.

Key parameters and benefits

• Versatility: The arrester is designed for installation in TN/TT networks, ensuring compatibility with various electrical installation configurations.
• High efficiency: Protection level ≤1.5kV guarantees effective limitation of surges to a safe level.
• High durability: Maximum discharge current Imax of 60kA and rated discharge current In at 30kA indicate high resistance of the device to intense surges.
• Fast response: Impact current Iimp at 10kA ensures a quick response to sudden voltage spikes.
• Safety: Compliance with PN-EN61643-1 standards guarantees compliance with stringent safety standards.
• Durability: Wide ambient temperature range (-40°C to +70°C) enables operation in harsh environmental conditions.
• Compact size: Occupies 4 modules on a TH35 rail, allowing for easy integration with the existing switchboard.
• Low residual current: Parameter I(pe) of 30µA minimizes the influence of the arrester on the operation of devices connected to the network.

The KSD-T1+T2 arrester is an investment in the safety and reliability of the electrical installation – both for professionals involved in the installation of surge protection systems and for end-users who care about protecting their equipment. Manufactured in the European Union by the renowned company KANLUX S.A., it guarantees high quality workmanship and long-term operation.
