Thruster motor power supply (12 V / 24 V):
These values are given as an indication, assuming that the batteries are charged at
100% and in charge, that is either 13.8V or 25.4V.
The performance data of the is measured with an approx. consumption of 680A and 11V
for the CT100, or 430A and 22V for the CT125, at the motor’s connections.
Please refer to the characteristics given by the manufacturer of the batteries that will be
used (see section 9 “Batteries”).
Power wiring:
Measure the shortest and most direct route possible between the battery(ies) and the
electric motor; remembering to allow for both “positive and negative” cables.
Recommended cable sections:
Cable lengths CT100 12V CT125 24 V
L ≤ 5 m (2,5 x 2) 70mm² 50mm²
5< L ≤ 10 m (5 x 2) 100mm² 70mm²
10 < L ≤ 15 m (7,5 x 2) 150mm² 95mm²
15< L ≤ 20 m (10 x 2) 200mm² 120mm²
For all connections, use appropriate terminals for the cable sections chosen.
It is possible to reduce the cable section to facilitate easy connection but only over a
short distance. In this case, appropriated crimp fittings should be used at the
connections.
Please consult the "Electrical installation" diagram p. 11 for more information
8. MAIN POWER FUSE
Fuse sizes for overcurrent protection are to be determined on the basis of the cable
sections in the circuit and NOT the amperage drawn by the appliance (thruster motor) in
the circuit.
Thruster Maximum Amperage Max Power Fuse size
CT100 / 12V 550A 315
CT125 / 24V 330A 200A
9. BATTERIES
Thrusters are high amperage consumers with instantaneous demands, thus, we
recommend you use maintenance-free “starting” type batteries, with high CCA outputs.
Example:
Battery: Exide Maxxima900 12V
Capacity: 55 Ah
CCA: 800
