Heavy-duty IP65 rated RCCB
FDB Electrical has introduced the IP65 rated FDB 19 series of electrical protection devices for heavy-duty applications. The units combine a variable sensitivity and time delay RCD, together with a 3 pole MCCB or On Load Switch + solid Neutral (minimum 15KA) to provide overcurrent and short circuit protection (4 pole option available).
A standard feature of the unit is its non-fail safe operation, making it suitable 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. Specifications of the series cover 380/440V with tripping levels adjustable from 10mA to 640mA and 100mA to 6.4A as standard (1-64A also available). An Earth Fault Ammeter can also be fitted to the front of the enclosure to indicate levels of Earth Leakage.
Load current ratings available cover 15A to 400A. The complete assembly is housed in a lockable IP65 Sheet metal or IP54 GRP enclosure to ensure resistance to rough treatment
