This is a Zinsco RQ38, 30 Amp plug-in 2 pole circuit breaker. I believe the only reason this one lasted is because it powered a dryer receptacle in a home with a gas dryer, and was never used. It's 3/4" wide.
(It's got "IQ65" stamped in a small emblem on the side; possibly the designer's test score?)

How do you like it?
Do you have any other candidates for the honor?
