MIL-PRF-55629/20G
When circuit breakers without auxiliary contacts are installed in new equipment, replacement spares should possess
this feature since it is more economic for the DoD to stock one version of this item instead of two. Therefore, stock
numbers should not be requested (or assigned) for this special PIN.
