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.
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

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.
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.
