Maretron CBMD12 12-Circuit Bypass Module for NMEA 2000 Systems with Manual Control and Overcurrent Protection

The Maretron CBMD12 12-Circuit Bypass Module provides a reliable manual control solution for marine and industrial power systems utilizing NMEA 2000 networks. Designed to work seamlessly with the Maretron CLMD12 load controller, this module allows for manual ON/OFF operation of up to 12 different loads, ensuring operation continuity in case of network failure or controller malfunction. Its robust construction supports a maximum current capacity of 75 amps in 12V and 24V DC systems, making it suitable for a wide range of demanding applications. The CBMD12 employs standard ATC fuses for overcurrent protection, helping safeguard wiring and connected loads from electrical faults. Each circuit is managed with Carling Curvette Rocker Switches, which enable manual toggling without arcing, reducing wear and potential electrical hazards associated with traditional switching mechanisms. Unlike digital switching products, this module does not require fuse removal to override loads, decreasing the risk of connection degradation or ignition hazards. It features two outputs rated for up to 12 amps, six outputs rated for 10 amps, and four outputs rated for 5 amps, providing flexible control options across different load requirements. The module is compatible with both 12V and 24V DC power systems, making it versatile for various marine or industrial setups. It is important to select appropriate fuse ratings for each load to ensure proper protection and system reliability. Note that the CBMD12 does not support paralleled outputs or circuit dimming, focusing solely on straightforward manual control and overcurrent protection. This product is designed for professional installation and may not be returned to the point of purchase, so direct manufacturer contact is recommended for support or warranty concerns.
