Circuit breaker compatibility is determined by UL testing and listing. OEM breakers are made by the same company that manufactured the panel. UL-Classified breakers are made by a different manufacturer but tested and certified for use in specific panel types. Never install a breaker that isn't listed for your panel — even if it physically fits. This violates NEC 110.3(B) and creates fire/shock hazards.
