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.

For further information please see our Online store or contact us in Isleworth to discuss your needs.

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.

CB514_medium CT from FDB

Here at FDB Electrical we have a wide range of core-balance transformers (CTs) for use in monitoring supply conductors together with with earth leakage relays (ELRs and ELCBs)  and MCCBs where the CT  provides a warning signal from the incoming cable, giving advance information to the trip device so ensuring greater safety for personnel and equipment.

We have these available from our online store  from 16mm up to 240mm to accommodate most cable sizes.

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
