The second picture is of a circuit breaker I removed from the old Seward Station. Patent 1901. MFG 1911, installed 1920. Abandoned in place 1975. Removed by Frank Z in 2004. The wooden sign above it says 440 VAC. Note the carbon contact attached to its arcing contact. The arcing contact and live electrical components are exposed to the operator. I gave a second set to the Discovery museum in Johnstown. There are a few more of these left waiting for the wrecking ball.

Kewl! It looks like it has both inductive and thermal trips.
