BEP Marine

<h3>About BEP Marine</h3><p><strong>BEP Marine</strong> has been a cornerstone of the marine electrical industry since its founding in 1995 in Auckland, New Zealand. Rooted in New Zealand's world-class yachting culture — a scene shaped in no small part by successive America's Cup campaigns — BEP Marine built its reputation on engineering electrical products that could survive the most demanding conditions on the water and beyond. Today, the brand is part of the Navico Group under Brunswick Corporation, and its products are specified as original equipment by leading boat, emergency vehicle, and RV manufacturers worldwide.</p><h3>Engineering for the Harshest Environments</h3><p>What separates BEP Marine from generic electrical suppliers is a relentless focus on real-world performance. Every product in the BEP lineup is designed to meet exacting performance specifications, capable of withstanding prolonged exposure to salt air, moisture, vibration, and extreme temperatures — both at sea and on land. BEP backs this confidence with a &quot;Trusted Quality&quot; 5-year warranty across their product range, a testament to how thoroughly their components are tested before they reach your vessel.</p><p>BEP's engineering culture also prioritizes ease of integration. Whether you're wiring a simple single-battery sailboat or a complex multi-bank power system on a large cruiser, BEP products are designed to slot into both straightforward and comprehensive electrical architectures without hassle. Their innovative product lines — including the CZone digital switching system and the Pro Installer series — represent the cutting edge of onboard power management, allowing boaters to monitor and control circuits from touchscreen interfaces and minimizing valuable space in crowded electrical panels.</p><h3>Core Product Categories</h3><p>BEP Marine's catalog spans the full spectrum of marine power management. At the heart of their offering are <a href="/11486-bep-marine-battery-switch-12204">battery switches</a>, where BEP has pioneered design innovations for decades — from compact On/Off isolation switches to high-capacity selector switches rated at 400A continuous and 600A intermittent. Their award-winning EZ-Mount line (recipient of the prestigious METS DAME award) features an industry-standard footprint that clusters with other Pro Installer components, saving precious onboard space.</p><p>For remote power control and automated charging management, BEP's <a href="/11486-bep-marine-solenoids-202547">solenoids</a> allow boaters to switch high-amperage loads using low-current control circuits — essential for bow thrusters, windlasses, and other high-draw accessories. The Digital Voltage Sensing Relay (DVSR) automates second battery bank charging with exceptional efficiency.</p><p>Rounding out the core lineup, BEP's <a href="/11486-bep-marine-battery-disconnect-switches-200143">battery disconnect switches</a> deliver reliable isolation capability for single or dual battery banks, ensuring your vessel's electrical system can be safely de-energized for maintenance, storage, or emergency situations. Motorized disconnect variants allow remote operation, making them ideal for installations where the battery is difficult to access directly.</p><h3>Who Uses BEP Marine?</h3><p>BEP Marine serves both OEM boat builders and the marine aftermarket, with a product range trusted by recreational boaters, commercial operators, and emergency vehicle fleets across North America, Europe, Asia Pacific, and Oceania. If your application demands reliable, durable, and intelligently designed electrical components, BEP Marine delivers solutions built to go the distance.</p>

Product Details

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
  • Cranking Rating: 2500A DC
  • Operating Voltage: 9.5-32V DC
  • Function: On/Off
  • Stud Size: 2x 1/2" (12mm)
  • Dimensions: 4" L x 4" W x 4.33" H

The MD range of battery switches provides professional-grade switching solutions that reduce installation complexity while offering the capacity and reliability required for demanding marine electrical systems.
