the new SLO-BLO...is it LEAD FREE??? and why add the label?

All,

Thanks, I do understand that the intended application of the FAST-BLOW ...ie: electronic circuits or relays...SLO-BLOW used for high surge circuits like lights and motors.

Mainly I was confused as to why the newer fuses had the label SLO-BLO added?...the old ones had no label, so why add one now? New type of fuse?

All I can think of is the older, unlabeled fuses use a flat LEAD strip as the element...and the lead is now banned from manufacture?

The new fuses now labeled SLO-BLOW use a "twisted wire" element (which, I am guessing is lead free).

I suppose the newer "twisted wire" element, at first glance, looks similar to a FAST-BLOW fuse's single thin wire element, so they added the SLO-BLOW label.

Still confused me...anyone know?

Pete
