3.4.2 Breaker Connections
The CLMD12 breaker connections are made by connecting to the 12-pin J1 connector. The pin
number on the J1 connector corresponds to a breaker number, which is represented as an
indicator number in the 127501 Binary Status Report message or as a Connection ID in the
127500 Load Controller Connection & State message. The correspondence of the J1 connector
pin number to the channel number is detailed in the table below, along with the maximum current
supported by the channel.
