Square D Company Circuit Breaker, circa 1950
01
Artifact Overview
In the late 1800s, as companies began producing electricity to light cities, run streetcars, and power factories, homes and offices, new apparatus was needed to safely deliver and use electricity. Excess current in a circuit could damage electric lines and equipment. Circuit breakers protected electrical circuits by automatically interrupting the power flow during an event overload.
