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

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