Separator relay for 12 V battery system CT25 - CT100 times

Description

When installing a bow thruster, the battery disconnect switch (or a main power switch or solenoid rated for high currents) is essential for safety, equipment protection, and the reliable management of high operating currents.

Key Reasons for Using a Battery Disconnect Switch
High operating current: Bow thrusters draw extremely high currents during operation. A separate battery disconnect switch or a solenoid/circuit breaker rated for high currents can safely handle such a load. Standard boat electrical system switches and wiring are not always suitable for high-current circuits such as those found in bow thrusters.
Emergency power shut-off: If the bow thruster solenoid gets stuck in the “on” position or the insulation on the high-current cable is damaged and the cable rubs against the boat’s hull, a short circuit may occur. Using the battery disconnect switch, the bow thruster’s circuit can be shut off immediately right next to the battery.
Preventing accidental activation: When the battery disconnect switch is turned off—for example, after mooring at a dock—pets, children, or accidental activation of the control panel switch cannot start the bow thruster.
Preventing corrosion and battery drain: Isolating the bow thruster’s separate electrical circuit from the battery prevents unnecessary standby current—or leakage current—from being drawn when the system is not in use. At the same time, it reduces the risk of leakage currents and electrochemical corrosion that may occur in long, large-gauge cables.
