NF800-SEW and NF800-HEW Selective Breaking Correction Notice

This document announces a correction to the breaking capacity values for specific selective breaking combinations of molded case circuit breakers (MCCBs), specifically involving main breakers NF800-SEW and NF800-HEW paired with branch breakers NF125-RGV and NF250-RGV. The error was found in the general catalogue, technical note, and selection software (MELSELECT & MELSHORT2), and the corrected values are provided, though the individual breaker performance remains unchanged.
