Mechanical and Soldering Details
Reflow soldering parameters are specified for both Sn-Pb eutectic and Pb-free assemblies. Components may exhibit temporary changes in spark-over voltage post-reflow, with recovery within 24 hours.
Do not operate surge arresters in networks exceeding their maximum spark-over voltage.
Handle with care to avoid damage; surge arresters must not be dropped.
Ensure no solder bridges reduce insulation distances during mounting.
Use within 24 months after shipment for optimal performance.
