earth fault protection

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.

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.

Earth line protection devices from FDB Electrical

We have been specialists in industrial electrical protection equipment for a long time now and are able to offer our proven technology in component form to panel builders wishing to configure their own systems. This FDB range includes many panel mount devices and system elements.

For example the FDB EMGUARD earth line monitor range includes 110V, 240V and 440V units – the 110V unit in particular being of interest since this is a rating not commonly offered elsewhere. The EMGUARD series comply with BS4444 and offer 1-20 ohms impedance (adjustable), fully encapsulated and housed in a PA6 enclosure ready for chassis mounting.

Other components include the EFU62 VELEM combined earth fault and earth line monitor and the VEF series variable earth leakage protection relay. The EFU series includes a combined earth fault and earth line monitor and DC earth fault monitor, this compliments the EFR range of universal earth leakage protection relays, along with matching external CTs where required.

This FDB program of earth line protection devices enables panel builders and installers to complete full electrical protection systems to their own specifications – contact us to discuss configuration or order at our Online shop.

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
