BEP Marine 720-MDO Remote Operated Battery Switch 500 Amp 12/24V Optical Sensor

The BEP Marine 720-MDO is a remote operated battery switch designed to handle the increased electrical loads found on modern vessels. With a 500-amp continuous rating and 12/24V compatibility, this switch allows for installation directly alongside the battery, significantly reducing cable lengths and sizes for substantial savings in both copper cable expense and weight.

Advanced Optical Sensor Technology:

The 720-MDO features an enhanced optical sensor that provides versatile installation options. The optical sensor enables control of different voltage circuits beyond the main supply voltage—ideal for applications like controlling a 48-volt bow thruster from a 24-volt house supply. The main contacts can be isolated from the control circuit, allowing operation via a separate battery source, and the system maintains a low standby current draw of less than 5mA.

Key Features:

• Remote operation capability with manual override option to meet CE/ABYC requirements
• Mounts directly alongside battery to minimize cable runs and installation labor
• Can switch positive or negative lines for flexible installation
• LED status identification on remote control switch
• Compatible with BEP interchangeable labeling system (Item #713 or #715)
• Ideal for remote isolation of bow thrusters, stern thrusters, and high-current accessories

Technical Specifications:

• Continuous Rating: 500A DC
• Intermittent Rating: 700A DC
