606 Series High-Current SMD Fuse
RoHS
Pb
Description
The 606 series is the smallest cartridge fuse rated
at 500VAC with 40A to 63A current ratings and a
2,000A@500Vac interrupting rating. It is designed for
supplemental branch circuit (AC input) over-current
protection or other stages of power conversion where high
voltage is present. This series fuse is RoHS compliant and
100% Pb free.
