Mastervolt MasterBus Cable - 3M

The Mastervolt MasterBus Cable – 3M is the backbone of any modern marine electrical network, designed specifically for vessels that demand reliable data and power distribution across multiple systems. If you've spent years running integrated electronics on the water—GPS, autopilot, battery monitors, and auxiliary equipment—you know that a single weak link in your network cable can cascade into frustration at the helm. This 3-meter cable connects MasterBus-compatible peripherals and non-standard equipment through a dedicated interface, eliminating the need for multiple cable types throughout your boat's electrical infrastructure.

Built to Mastervolt's marine-grade standards, this cable handles both low-voltage data traffic and power delivery to connected devices without signal degradation or voltage drop—critical when you're running navigation and monitoring systems in parallel. The 3-meter length provides flexibility for typical topside and cabin routing without excessive slack or the need for splicing, while the connector design ensures weathertight connections that won't corrode or fail in salt spray environments. At just 0.2 lbs, the cable is lightweight enough for easy installation through cable runs and conduit, yet robust enough to withstand the mechanical stress of a working vessel underway.

Boaters upgrading or expanding their Mastervolt systems will find this cable essential for bridging gaps between MasterBus-native equipment and peripheral devices that require an interface module. Whether you're adding a new battery management system, expanding your DC distribution network, or integrating third-party sensors, the Mastervolt MasterBus Cable – 3M (SKU CW63364, MPN 77040300) eliminates guesswork and ensures compatibility across your entire electrical ecosystem. It's the kind of straightforward, purpose-built component that separates a well-maintained marine electrical system from one that's held together by workarounds.
