Scope

Main technical content: This document specifies the basic requirements, classification, characteristics, marking and product information, normal use conditions, structural and performance requirements, test methods, inspection rules, packaging, transportation and storage, and quality commitment content for F-type and B-type residual current operated circuit breakers (hereinafter referred to as RCDs). This document is applicable to F-type RCCBs (residual current operated circuit breakers without overcurrent protection) and F-type RCBOs (residual current operated circuit breakers with overcurrent protection) with an AC rated frequency of 50 Hz, 60 Hz, or 50/60 Hz, used in electrical devices powered by phase lines and neutral lines or phase lines and grounded intermediate conductors by inverters. It can provide protection against rated frequency AC sinusoidal residual current, pulsating DC residual current, and possible composite residual current.
