Ratio Electric has developed the Shore Power Smart Box (SPSB) especially for the safe charging of your electric boat.
The SPSB protects your boat against overload while charging your batteries at maximum speed.
The SPSB is connected to the boat with a power cable that uses a type 2 male and female plug. Similar to electric vehicles.
The SPSB has an integrated earth leakage AC (30mA) and DC (6 mA) protection.
