FDB Electrical Ltd has completed a contract to supply FDB19/STS special-purpose power supply units for use by Royal Marines landing craft such as the RM rapid-response/patrol boat.
The FDB19/STS is a specially configured version of the standard FDB19 Heavy Duty Adjustable RCCB designed to be mounted on offshore pontoons that are supplied from shore based transformers.
Once moored, landing craft can plug into the FDB19 and recharge on-board batteries and ancillary equipment. Housed in GRP enclosures with glazed panel to provide sight of the various LED status indicators, the equipment comprises a 60A, 16KA MCCB feeding an electro/mechanically interlocked socket outlet.
Electrical protection is via an EFU15 multi-function RCD and Emguard Earth Continuity Monitor. External Test and Reset buttons facilitate ease of operation and testing.
The standard FDB19 series combines a variable sensitivity and time delay RCD, together with a triple pole MCCB (minimum 15KA) to provide overcurrent and short circuit protection.
The standard FDB19’s non-fail safe operation is ideal for primary breaker installations or those that are unmanned or prone to supply interruption. A fail-safe version requiring reset of MCCB on restoration of a supply interruption is also available.
