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).

MOC Installation Instructions
There are two MOC versions available: with and without a driver for the test position. The version with only one drive is generally used for
fixed-mounted circuit breakers.
- OPEN the circuit breaker and discharge the closing spring
- Remove circuit breaker from cradle
12.8.2.1 Installing the coupler
In order to interface the MOC assembly (mounted in the circuit breaker compartment), the circuit breaker must be outfitted with a
coupler (see Figure 1).
In order to install the coupler, the clear plastic plug in the sidewall of the circuit breaker (see Figure 2) must first be removed.
Facing the breaker, the plug is on right sidewall. This is easily accomplished by levering with a small screwdriver.
