Abstract
An electrical contact apparatus having low silver content and defined thickness and length geometry. The electrical contact apparatus has a contact body made of a silver-containing alloy having SC≤60 wt. %, and having L/T≥5.4, wherein L is a longest contact length dimension of the contact body, T is a maximum contact thickness dimension of the contact body, SC is the silver content in wt. %, and L/T is a contact dimension ratio. Electrical contact assemblies, circuit breaker electrical contact subassemblies, and methods of operating a circuit breaker electrical contact subassembly are disclosed, as are other aspects.
