K. 12 and IEC61643-1 Dimensions Tin-plated Packaging Cautions and warnings ● Surge arresters must not be operated directly in power supply networks ● Surge arresters may become hot in case of longer periods of current stress (danger of burning). ● If the contacts of the surge arrester are defective, current stress can lead to the formation of sparks and loud noises. ● Surge arresters may be used only within their specified values. In case of overload, the head contacts may fail or the component may be destroyed. ● Damaged surge arresters must not be re-used. DC Elec.
