KAIC Ratings for Industrial Control Panels: What You Need to Know
KAIC ratings apply to individual protective devices like breakers and fuses, while SCCR ratings apply to complete control panel assemblies. Many facilities assume component ratings automatically ensure panel compliance, but the lowest-rated component limits your panel’s overall protection. Underrated panels create serious safety risks and code violations. Getting this right requires professional fault current studies and proper component selection from the start.
