It sits in the Molded Case Circuit Breakers subcategory under Circuit Breakers, Fuses & Protection.
The C-curve characteristic means the breaker trips at 5–10 times rated current (50–100 A for this 10 A unit), suited for inductive loads like small motors and lighting banks where inrush is moderate. The 2-pole configuration protects both phase conductors in a single-phase or split-phase circuit.
