Surge arrester KSD-T2 275/40 1P KANLUX IDEAL TS 23130

Electrical installation protection with surge limiters KSD-T2

This KSD-T2 275/40 1P surge limiter from KANLUX, part of the IDEAL TS series, is a key element in protecting electrical installations from the effects of surges. Designed to protect buildings without a lightning protection system or with a cable connection, it provides effective protection against induced and switching surges. This is particularly important in places exposed to frequent voltage changes or when connecting devices sensitive to network fluctuations.

This limiter, classified as Type 2 (class II), complies with the PN-EN61643-1 standard, guaranteeing high quality and reliable operation. It provides protection in zone 1-2 according to EN62305, making it an ideal solution for a wide range of applications. Manufactured within the European Union, it is characterized by solid workmanship and compliance with European safety standards.

Characteristics and installation

The KSD-T2 limiter is mounted on a TH35 rail and is intended for use indoors. Its compact size (1 module) allows for easy integration with existing electrical infrastructure. Screw terminals facilitate quick and safe installation by a qualified installer. The device operates at a rated voltage of 230V AC and a frequency of 50Hz, making it compatible with most standard electrical installations.

It is worth paying attention to the key technical parameters: the maximum discharge current Imax is as high as 40kA, and the rated discharge current In is 20kA. The voltage protection level U(p) ≤1.3kV ensures effective reduction of surges to a safe level. Additionally, the limiter is characterized by a low residual current I(pe) of only 30µA, which minimizes the impact on the operation of connected devices. The operating temperature range from -40°C to 70°C and humidity from 5% to 95% guarantee reliable operation in various environmental conditions.
