Αdvantages:

• Type F οffers the same range of protection and functionality as a Type A RCD; this means that release with sinusoidal AC currents as well as pulsating DC currents. In addition to this, they are capable of detecting residual currents from mixed frequencies of up to 1000 Hz, which can often occur on the outgoing feeder side of single phase frequency converters.
• Type Β In addition to release residual current waveforms of type A, B type RCCBs are used to detect smooth DC residual currents. B Type RCCBs are recommended for use with EV Charge and drives and inverters for supplying motors for pumps, lifts, textile machines, machine tools.
