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

FDB Electrical custom built power protection panels

Here at FDB Electrical we specialise in high end industrial and Military spec electrical protection devices, and have many well proven standard configurations to choose from – with many available from our online store – others to order as shown on our website – but of course we often get requests for something a bit different and that is where our extensive expertise comes into play. Whether you are looking for a DC immune device for a rail related installation or an IP 66 three phase unit we can custom build to meet your needs – for land based, shore line, ship installation, hangers, workshops, industrial units, institutions or domestic application – contact us to discus your special needs.

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.
