VDF-63 is a range of type RCDs/RCCBs which can detect wide residual currents like AC 50Hz,AC 50 pulse,smooth DC,AC>50Hz
What are the benefits of this type b RCD?
1. Type B RCD has very powerful functions, has full type AC, type A and type F features plus detection ability of smooth DC currents.
2. Wide applications: EV charging station,frequency inverter,elevator,solar PV system.
3. 30mA,100mA,300mA and 500mA residual current
4). Use the top quality metal and plastic materials: PA66 flame-resistant plastic for enclosure to make the product uninflammable,avoid the possible fire; top red copper for contacts to ensure the reliability and durability of the product.

• It can be installed in either single-phase networks or three-phase networks with or without neutral
• Ultimate protection of people and equipment
Types
• The RCCBs are further divided into types depending on the operating function:
•Type AC: For which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising.
• Type A: For which tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether
suddenly applied or slowly rising.
• Type F: Offer 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 1000Hz,
which can often occur on the outgoing feeder side of single phase frequency converters.This prevents undesirable interruptions to the
electrical supply if,for example, pulsed leakage currents of up to ten milliseconds occur at activation of filter capacitors.
• Type B: In adition 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… since they recognise a continuous fault current with low level ripple.
Tripping Sensitivity Data
• RCD with a rated residual current of maximum 30 mA are used for personnel, material and fire protection, as well as for protection
against direct contact
• RCD with a rated residual current of maximum 300 mA are used as preventative fire protection in case of insulation faults
• RCD with a rated residual current of 100 mA co-ordinated with the earth system according to the formula l△n< 50/R, to provide
protection against indirect contacts
• RCD with a rated residual current of 10 mA are primarily used in areas that reprent an exist risk for personnel
