Notes|Breaking capacity = maximum interrupting rating at rated voltage, DC unless noted; AC and DC ratings differ and are shown separately where applicable.
|Voltage and current ranges are the envelope across the listed series — individual catalogue numbers cover a narrower band.
|Ratings per the corresponding Bussmann datasheet and UL / IEC standard shown in each row; always confirm against the dedicated datasheet before specifying.
