Maretron CBMD12-R 12 Circuit NMEA 2000 Bypass Module with Fuse Pack and Jumper Wires

The Maretron CBMD12-R is a versatile 12-channel bypass module designed for NMEA 2000 networks, providing manual control of loads in marine and other DC power systems. With a maximum current capacity of 75 amps at 12V and 24V DC, this module ensures reliable operation across various power configurations. It is ideal for systems where manual override of loads is necessary, especially during network or controller malfunctions. The CBMD12-R features standard fuses for overcurrent protection and utilizes Carling Curvette Rocker Switches, which allow for smooth, arc-free manual operation of each load without the need to replace fuses during overrides. This design minimizes electrical wear and reduces the risk of ignition caused by fuse movement or degradation.

The module supports up to 12 outputs, with each output rated for different maximum currents: two outputs at 12A, six at 10A, and four at 5A, making it suitable for a wide range of load sizes. Compatible with both 12V and 24V DC systems, the CBMD12-R provides flexible integration into existing marine electronics setups. Its robust construction and protection features include overcurrent protection via ATC standard fuses, ensuring each load is safeguarded against electrical faults. The module does not support circuit dimming or paralleled outputs, emphasizing its dedicated switching functionality and reliability.

Designed for ease of installation and operation, this bypass module allows for quick manual control directly at the switch, bypassing digital controls and preventing potential system failures. It is recommended that fuse ratings be matched to load requirements to maintain system safety and performance. As a non-returnable product, any issues should be directed to the manufacturer for support, ensuring proper handling and technical assistance. The Maretron CBMD12-R is a critical component for marine or mobile power systems requiring manual load management and enhanced safety features, delivering dependable performance in demanding environments.
