• Specify packaging code (insert packaging code prefix before part number)
e.g., BK- (or BK1-/TR2-) S505-1-R
• Specify option codes if desired (for axial leads, insert “V” between catalog
series and amp rating) e.g., BK-S505-V-1-R

1. Interrupting ratings: 500mA to 10A were measured at 70% to 80% PF on AC,12A was measured
at 100% PF on AC.
2. Typical DC Cold Resistance (measured at <10% of rated current).
3. Typical Pre-Arching I
2
t (measured at listed interrupting rating and rated voltage if not specified);
With "X" specified, the typical I
2
t value is measured at 10 times of rated current under DC.
4. Typical Voltage Drop( Voltage Drop was measured at 20°C ambient temperature at rated current).
5. No room for "CSA" & "KC" on the fuse endcap for Non-V Rev. No room for "IMQ", "CQC' or "KC"
on fuse endcap for -V Rev.
6. CQC only.
