SIEMENS Shore Connection Unit with Arc Fault Detection Device (AFDD) and Circuit Breaker (RCD/RCCB)

Never been seen before!
Protection for cables, operators and against fire in a 230 V shore power unit.
This unit provides total protection in case of residual current, short circuits and overloads, as well as arcs which can occur in 230 V installations with loose terminal/plug connections, cable breaks or insulation damage, or with defective connection lines.
Common installations with RCDs and RCCBs cannot detect possible arcs in defective electrical equipment and it is statistically proven that arcs in electrical systems are among the most frequent causes of fire.

CAUTION:
When connecting the device, pay particular attention to the position of the L and N connections, which is only guaranteed with proper CEE plug connections. A Schuko plug connection or lengthening the feed cable is not permitted and should be avoided. Always make sure the L1 and N phase position is correctly connected and does not change, this must be permanently monitored. If you cannot guarantee this, the reverse polarity protected version should be used.

If you sleep on board your boat or caravan, and at the same time run chargers, fan heaters or cooling devices, you should use this innovative and compact shore power unit for an all-round safe AC power supply and to avoid possible fires caused by electrical equipment in the on-board AC network!


Small but nice!
The combination of a compact SIEMENS RCD/RCCB breaker and innovative AFDD fire circuit-breaker only requires the space of 2 dividing units, 1 dividing unit = 17.5-18 mm) in a small distribution box.

Residual Current Device / Circuit Breaker (RCD/RCCB)
The integrated SIEMENS residual current circuit breaker ensures the required personal protection for residual currents > 30 mA and short-circuit and overload protection for currents of 16 A. It works exactly the same as previous (RCD/RCCB) switches, but takes up considerably less space.

Fire Protection Breaker (AFDD)
The integrated SIEMENS fire protection breaker (Arc Fault Detection Device, or AFDD for short) first detects dangerous electric fault arcs, such as those that can occur at serial line damage points, i.e.. non-secure contacts such as loose screw or plug contacts. These faults are not detected by the RCD/RCCB breaker!
The AFDD also detects arcs that can occur as a result of insulation faults between active conductors or against the protective conductor.
In both cases, the circuit is quickly and reliably broken, preventing electrically ignited fires.
Insulation faults occur on board, for example, due to vibrations, thermal expansion and shrinkage, mechanical stress, corrosion and ageing.
