Maretron 12-Circuit DC Load Bypass Module

The Maretron CBMD12 is a 12-channel bypass module for the MPower CLMD12 DC load controller. It gives manual on/off control of each load if the CLMD12 malfunctions or the NMEA 2000 network fails. It handles up to 75 amps on 12 or 24 volt systems.

Twelve Carling Curvette rocker switches control the loads, and they don't arc when manually overriding a circuit. Overcurrent protection uses standard ATC fuses. Unlike some digital switching systems, you never have to move a fuse, which can degrade connections or create an ignition risk.

Outputs match the CLMD12: two at 12 amps, six at 10 amps and four at 5 amps. The bypass module doesn't support paralleled outputs or dimming, and the fuse pack and jumper wire are not included. Check the available mounting space and surrounding hardware before installation so a correct part number does not turn into a clearance problem. Browse more marine networking.
