Joe - Damn. There goes my electrical merit badge. Mea Culpa. Revamping my presentation as we speak. The Bussman AGC spec sheet tells the tale and seems to ping to a 1A fuse having a typical drop of 0.31Vdc. http://www.cooperindustries.com/cont...AGC_Series.pdf
About Klixon 7277/7274 breakers. I read the specs and don't see it mentioned that it can be used as a switch like the Tyco. Only a mention of an option for an "auxiliary switch". Also, the maximum voltage drop for the 5A Klixon model is 0.25Vdc versus that of the Tyco which is 0.15Vdc. https://www.sensata.com/sites/defaul...ata sheet.pdf and https://www.alliedelec.com/m/d/6526f...72ec951f9f.pdf.
My $0.01 (de-rated).

Similar to Tyco, rated at 5000 cycles loaded, 10,000 unloaded. Also, the Tyco voltage drop is actually 0.195V, so they're pretty close. Tyco specs resistance as 0.03 ohms +/- 30% so max is 0.195, Klixon specs 0.25V drop max at max current. That Bussmann spec is typ, they don't spec max.
