It mounts externally to the breaker assembly, not inside the breaker housing, so panel layout must accommodate the additional footprint alongside the breaker. ## Compatibility and current ranges This CT is specified for use with 3VA6 breakers rated 600 A, 1000 A, or 1200 A, and with 3VA2 breakers rated 630 A, 1000 A, or 1250 A. The neutral CT provides the residual-current measurement path for the electronic trip unit; without it, the breaker cannot detect ground faults on the neutral leg. Verify the breaker frame rating matches one of the listed values before ordering — the CT is not a universal fit across the entire 3VA family.","metaTitle":"Siemens 3VA9677-0NA11 External N-Conductor CT, 600-1250 A","metaDescription":"Siemens 3VA9677-0NA11 external current transformer for N-conductor, compatible with 3VA6 (600/1000/1200 A) and 3VA2 (630/1000/1250 A) breakers.
