6) any NMEA 2000
network-connected keypad or VMM-Series network-connected switches, or
7) any NMEA 2000
(please refer to Appendix A for details).
The breakers can be monitored and/or controlled through use of the Breaker/Switch
component in the Electrical Distribution category of the Maretron display products listed above.
In addition, the current through each breaker may be monitored through the Breaker/Switch
Current component in the Electrical Distribution category of Maretron display products.
Since the output channels are implemented by Electronic Circuit Breakers, if the NMEA 2000
power is removed, all breakers will revert to the open (OFF) state. The state that the breaker
will be in when the NMEA 2000 power is restored can be configured to be ON, OFF, or in the
last state the breaker was in before power was removed.
2.5.1 Electronic Circuit Breakers
The 12 high-side output channels are switched with MOSFETs connected in a back-to-back
arrangement so that back-feeding is not possible when the breaker is turned off.
All output channels employ the following:
• Latched shutdown overcurrent detection with reset
• Overcurrent surge allowance that prevents overcurrent latch tripping when starting high
surge loads such as incandescent lamps
The table below shows the connection and maximum current capacity for each ECB.
