12.8.1 MOC Versions

The MOC device may be ordered in two versions for drawout circuit breakers:
The auxiliary contacts, in the "Connect Only" version of the MOC, only change state when the circuit breaker is opened/closed while it 
is in the "CONNECTED" position within the circuit breaker compartment. There are two distinct models of the "Connect Only" MOC, one 
for circuit breaker frame size 2 (WLMOCC) and a second for circuit breaker frame size 3 (WLMOCC3).
The second version is known as the "Test and Connect" version. In the "Test and Connect" version, the auxiliary contacts change state 
when the circuit breaker is opened/closed while it is in the "TEST" or "CONNECTED" positions within the circuit breaker compartment. 
Like the "Connect Only" version, there are two distinct models of the "connect only" MOC, one for circuit breaker frame size 2 (WLMOC) 
and a second for circuit breaker frame size 3 (WLMOC3).
