Description
Maretron CBMD12 12-Circuit Bypass Module | Boat Supply Store
Navigate critical electrical system failures with the Maretron CBMD12, a robust 12-circuit manual bypass module designed to provide direct control over DC loads when digital systems falter. This unit supports up to 75 amps across 12V and 24V DC systems, ensuring operational continuity for essential equipment, whether you're offshore fishing in the Gulf or navigating coastal waters. Its integration with the CLMD12 DC Load Controller Module and utilization of standard ATC fuses offer a reliable, no-arcing manual override solution, preventing degradation or ignition risks associated with fuse manipulation.
Key Features
- Reliable manual ON/OFF switch for each of the 12 individual loads.
- Essential redundancy provides power to each load during CLMD12 malfunction or NMEA 2000® network failure.
- Durable control via 12 high-quality Carling Curvette® Rocker Switches.
- Safe operation with no arcing during manual load overriding.
- Protective utilizes standard ATC fuses for overcurrent protection.
- Versatile supports both 12V and 24V DC power systems.
- Preventative does not require moving fuses, eliminating degradation or ignition risk.
- High capacity handles a 75 Amps maximum current load.
