Earth line protection devices from FDB Electrical

We pride ourselves on our range of AC and DC panel mounting items including RCDs, Earth Continuity Monitors and special purpose electrical protection devices compliant with BS4293 which we have available ex-stock for the specialist panel builder. These items can be reviewed and ordered direct from our Online store.

The range includes multi-range protection levels including pre-set and user adjustable types with solid state circuitry for immunity to voltage transients and DC components.

Associated core balance transformers are available in a range of sizes as is a suitable panel meter (EFU10/M) and conveniently sized RCD Test Set.

General purpose overload/short circuit and DC immune protection from FDB Electrical

Our FDB11 is a general purpose RCD panel unit providing overload and short circuit protection for industrial, academic, institutional and corporate applications. Installation is quick and easy with the FDB11 housed in a sheet metal enclosure.

Three enclosure sizes of FDB11 are available, 10 to 32 amp, 40 to 63 amp and 80 to 100 amp, conforming to BS4293 and BSEN60898.

In addition the FDB11 has been developed for specialist use to protect against induced DC current which can otherwise cause nuisance tripping in AC equipment adjacent to high voltage DC lines on railways. This is important in nearby offices, retail outlets and café/restaurants for example. The FDB11 is approved by Network Rail for these situations.

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
