Class I surge arrester

electronic equipment

SPCT2 surge arrester types are the most common installed surge protection devices designed for all low voltage electrical installations. This surge protection devices are often required by the national wiring regulations. • SPD-type T2 according to standard EN 61643-11 • Maximum continuous operating voltage (UC): 75 – 580 VAC • Test class II according to IEC 61643-1+A1 • Available with auxiliary contacts • Available with already installed busbar for easy and fast installation on RCDs Designed to protect most electrical consumer installations against switching overvoltage or indirect lightning strikes. At the very least T2 devices are recommended and are already mandatory in many European countries. Installation of surge protection devices is intended to ensure voltage limitation in accordance with insulation coordination, avoiding sparking which could cause a fire. Overvoltage protection devices should be installed to reduce the effects of overvoltage. This applies to the electrical systems of all buildings from residential homes up to hospitals, communications infrastructure, and other public buildings, aswell as commercial/industrial sites, for example hotels, banks, shops and factories.
