GB/T 22794-2008
AbolishedType B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses (Type B RCCBs and Type B RCBOs)
家用和类似用途的不带和带过电流保护的B型剩余电流动作断路器(B型RCCB和B型RCBO)
Application Summary AI generated
This standard specifies technical requirements for Type B residual current devices (RCCBs and RCBOs) that detect AC, pulsating DC, and smooth DC fault currents. It applies to household and similar electrical installations where equipment like variable frequency drives, inverters, or battery chargers may generate complex leakage currents. The standard ensures these devices provide reliable protection against electric shock and fire hazards in circuits containing non-sinusoidal or DC residual currents.
