In order to be able to quickly interrupt the power circuits in the event of technical problems, electrical installations on boats must be equipped with a master switch. The only genuine source of danger in a power circuit under 42 volts is defective contacts. These can cause local overheating and thereby lead to the risk of fire. Possible short-circuit currents are also a danger in relation to this, as they can irreversibly damage the battery. For this reason, it is recommended to use a pre-assembled cable set, which should include additional short-circuit protection as well as a master switch.Torqeedo draws on a meticulous selection of materials and uncompromising quality for all of its cable connections, switches, connectors and fuses. This means that minimum loss and a high standard of safety are guaranteed. Torqeedo offers pre-assembled cable sets with master switch, fuse and jumper cable for series connection of two 12 V batteries for the Cruise series models. The cable sets are completely pre-assembled and are equipped with high-current connectors for convenient installation. This means that a Cruise electric motor can be safely installed in just a few minutes with the help of a regular spanner. Torqeedo cable connections and sets must be able to handle peak currents of over 80 amps. For example, the Cruise 2.0 model with an input power of 2,000 W and a voltage of 24 V has a current flow of some 83 amps. For this reason, Torqeedo uses cables with 25 mm2 cross sectional area for cable connections and cable sets. With a cable run of 5 metres between motor and battery, this results in a loss of approximately 24 W or 1.2% of the overall performance. This minimising of the power loss ensures a high degree of motor efficiency and offers the additional benefit of safety, as high loss increases the danger of local overheating. 9103 Cruise 2.0 S Powerfull 24 V motor, short shaft version, incl. charge indicator 9104 Cruise 2.0 L Powerfull 24 V motor, long shaft version, incl. charge indicator 9301 Cable set Cruise 2.0 High current cables according to the recommendation of the German T�V, 25mm_ cross sectional area, max. connection distance motor - battery 3 m, master switch with fuse, battery connection cable also usable for serial connection of two 12 V batteries, including high current connectors and connecting diagram 9303 Cable set extension 2 m extension for Cruise cable set including high current connectors 9401 Electronic throttleright/top installation Remote control for Cruise 2.0, ready for connection with 6 m control cable 9402 Electronic throttleleft/top installation Remote control for Cruise 2.0, ready for connection with 6 m control cable 9502 Replacement propeller Cruise Particularly developed high efficency propeller for the torque technology and the range of performance of Torqeedo Cruise motors, fibreglass reinforced polyamide, 3-blade, 30 cm diameter (12")
