Default Where to find thermally-protected radial, wire-wound power resistors?

To summarize:

Wire-wound cermet, radial-lead 22.0 ohm, 10 watt, 5 percent, thermally-fused
@ 185c / 10A.

The original is a labeled SQF10W but I canšt find any reference to this
series. TT Electronics (irctt.com) might be the manufacturer. They have SQM
and CVF series resistors but a search for SQF turns up nada:

irctt.com/file.aspx?product_id=305&file_type=datasheet

Here's images of the remains of the original:

The internal fuse is clearly labeled 10A and 185c. Not sure if this means
it's only a thermal fuse rated at a maximum of 10A or it's a current fuse
rated at a maximum of 185c or if it's a thermal and current fuse.

Either way it's apparently more than just a resistor.

Help!!

Cheers.
