Notes:

The CSA Component Acceptance Mark appears on the device. As an alternative, where space does not permit, it may appear on the device package.
Maximum circuit voltage and applied fault current are to be limited on the application per the rated max V and max I.
In the tripped state, device temperature is maintained at approx 125C.
The "S" suffix indicates a slotted lead option.
For MF-S and MF-LS Series, the suffix "*" can be blank or the letter "S" for slotted lead.
Models marked with "#" may or may not have suffix "S" or "SS".
Model numbers may be followed by suffix(es) indicating different shapes of leads/terminals, plating of leads/terminals, colours of cover tape or packaging methods.
“†” indicates maximum one-hour post-trip resistance.
