RCDs

FDB 11 enclosed RCD protection unit

Our FDB electrical protection family of RCD and RCBO devices runs from the Multiway FDB 2 modular panel through the FDB 11 at 230V for general purpose building renovation upgrade and maintenance projects to the and the FDB 13, FDB 15 and FDB 19 3 phase units for new build installations. Also in the family is the FDB 27 MOD spec unit for aircraft or army hangers new build and replacement installations.

These proven units are a convenient option for new or replacement installations offering long life and reliability – they are available from our Online store here.

Electrical protection units from FDB Electrical

The use of RCD electrical technology has become commonplace in all areas of building services where the safety and convenience of this type of protection is of great value – but RCDs and their “sister” MCBs often need to be housed in specialist enclosures which provide for the integration of a number of devices in a custom system. Here at FDB Electrical we have created  the FDB11 as a unit which installers can readily customise and which also provides for the use of multiple units in  a grid layout. The facilities offered by the FDB11 are especially of value in the industrial and institutional arenas where capacities of 40A to 63A  and up to 100A can be accomodated

  • General purpose RCD with overload and short circuit protection
  • Steel, surface mounting enclosure c/w knockouts (IP20)
  • Conforms to BS4293 (RCD); BSEN60898 (MCB)
  • IΔn: 20mA; 30mA or 100mA

FDB panel mounting protection units

Our range of specialist panel mounting electrical protection items available at our Online shop includes RCDs, Earth Continuity Monitors and special purpose electrical protection devices  compliant with with BS4293. These enable panel builders and installation engineers to configure their own electrical protection systems within an application specific enclosure or cabinet providing appropriate environmental protection.EFR1 Earth Leakage Relay

We offer both AC and DC types of panel mounting components to multi-range protection levels including pre-set and user adjustable types. Where appropriate we use solid state circuitry to offer immunity to voltage transients and DC components. The range includes associated core balance transformers in a range of sizes to suit each installation. EFR-52 earth fault relay

For visual monitoring we have the EFU10/M Panel meter and for testing we have a portable series 6 RCD test set.

 

FDB13 - 400V 3 phase DC immune protection from FDB ElectricalOur range of Electrical Protection devices is available at the Online store for easy reference and selection – this includes:

Enclosed units such as the FDB11 and FDB13 general purpose RCD housed units with overload and short circuit protection, also the FDB2 for multi-circuit protection in a single enclosure and the FDB21 for installations requiring interruptible RCD protection together with overload/short circuit protection.

FDB Electrical FDB19/STS provides ship to shore power for landing craftWhere external power is needed then we have the FDB27 ( also in MOD spec ) which provides protection for Ground Support Equipment – this range of earth leakage/earth monitoring devices was originally for for protection of personnel and plant in RAF/RNAS hangars but also has wider uses. Its sister the FDB27/M RCD Protection unit for Communications Vehicles is a range of special purpose RCD protection units for military communications vehicles with in-line filters.
