About the Auxiliary Contact
Adapter Use these instructions to install an external auxiliary contact adapter in
CENTERLINE 2100 Series Q…Y units with Cutler-Hammer Westinghouse
Circuit Breakers
(1)
(HMCP600, LD, HLD, LDC, MDL, HMDL, ND, HND,
and NDC).
This auxiliary contact kit (2100H-N23) is to be used with the following auxiliary
contacts: catalog numbers 2100H-N19 or 2100H-N20.

the OFF/O position.
2. Verify the parts list, see
Assembly of External Auxiliary Contact Parts .
3. Attach the external auxiliary contact assembly to the mounting plate by
using two 1/4-20 thread-rolling screws and torque to 55 lb•in (6.2 N•m).
Refer to Assembly of External Auxiliary Contact Parts.
4. Attach the actuator to the circuit breaker bail by using two 1/4-20
thread-rolling screws.
5. Position the actuator so the screws are centered in slots and torque to
55 lb•in (6.2 N•m).
6. Install auxiliary contacts (Catalog Number 2100H-N19 or 2100H-N20).
