Our FDB 11 is a modular range of general purpose earth leakage protection units complete with overload and short circuit protection, and approved by Network Rail for use in DC electrified areas. They are configured in a modular arrangement so that multiple units may be installed and added to over time to create a modular grid – so that as the power requirement increases then extra capacity may be added with more distribution units – which may be purchased from our Online shop.
