OUTLINE OF INVESTIGATION FOR US NAVAL COMMERCIAL OFF THE SHELF (COTS) THREE-POLE@ RATED MAXIMUM VOLTAGE 4.76@ 8.25@ AND 15KV@ AC@ VACUUM CIRCUIT BREAKERS@ DRAWOUT TYPE@ WITHOUT INTERNAL OVERCURRENT PROTECTION@ AND ACCESSORIES/COMPONENTS FOR USE ON NON-NUC
These requirements cover three-pole@ rated maximum voltage 4.76kV@ 8.25kV@ and 15kV@ AC@ vacuum circuit breakers@ drawout-mounted type@ without internal overcurrent protection@ and applicable accessories/functional components intended for use aboard non-nuclear Naval combatant ships in electrical assemblies (switchgear) installed on shock isolators (mounts). These requirements cover only the removable element (circuit breaker) and require testing in a representative switchgear interface as detailed in this Outline.
