Description
12 Circuit Bypass Module NMEA 2K without Fuse Pack & Jumper Wire For manual control of the loads, an optional MPower® 12-Channel Bypass Module (CBMD12) can be installed in conjunction with the 12-Channel DC Load Controller Module (CLMD12). The maximum current capacity for the CBMD12 is 75 amps in 12V DC and 24V DC power systems.
The Bypass Module provides a manual method (ON/OFF switch) to control loads by providing power to each load in case of a CLMD12 malfunction or a NMEA 2000® network failure. The CBMD12 utilizes standard fuses for overcurrent protection and 12 Carling Curvette® Rocker Switches for manual control of each load.
With the use of the Curvette rocker switches, there is no arcing that occurs while manually overriding a load. Furthermore, unlike other digital switching products, MPower does not require moving a fuse, which can cause electrical connections to degrade or the possibility of ignition.
It’s important to ensure that the current rating of the fuse for each load is appropriate to protect the load and the wiring for that load. Please note that the bypass module does not support paralleled outputs, since each circuit is controlled by a separate switch.
Additionally, the bypass module does not support dimming of circuits.

Marine Navigation & Instruments — frequently asked
- What’s the difference between a chartplotter and a fishfinder?
- A chartplotter shows your GPS position on electronic charts for navigation. A fishfinder uses sonar to show what’s below the boat — depth, bottom structure, and fish. Many modern units combine both, and networked systems can share data across displays.
- Do I really need a VHF radio?
- For safety, yes. A VHF radio is the primary way to reach other vessels and the Coast Guard, and a DSC-equipped VHF connected to GPS can transmit your position in an emergency. It’s more reliable than a cell phone offshore and is the recognized standard for marine distress calls.
- What is NMEA 2000 and do I need it?
- NMEA 2000 is a standard network that lets marine electronics — chartplotter, sonar, autopilot, sensors, engine data — share information over a single backbone. It’s not required for a simple setup, but it makes multi-device systems far easier to expand and integrate.
