Siemens 3VA5111-5ED16-1AA0 Circuit Breaker
Selection Trade-offs (SENTRON 3VA51 Series)
-
Pole count determines branch coverage: the seed is single-pole; alternate 3VA5111-5ED26-1AA0 (two-pole) and 3VA5111-5ED36-1AA0 (three-pole) share the same 110 A rating and series but serve multi-wire branch protection. Single-pole units protect ungrounded conductors only; multi-pole versions provide common trip and equipment isolation.
-
Approval agency scope varies across suffix variants: the seed carries CCC, CE, UL489, and VDE listings. Variant 3VA5111-5ED11-1AA0 adds CSA and EAC but omits VDE; variant 3VA5111-5ED12-1AA0 lists only CCC and UL489. Regional compliance requirements narrow the field of usable variants.
-
Termination identifier (NAV / AL / NUT) affects lug compatibility: the seed suffix -1AA0 denotes a nut-lug termination per the SENTRON family naming convention for the 3VA51 line. The -0AA0 variants (e.g., 3VA5111-5ED16-0AA0) use a box lug or crimp termination; selection depends on conductor preparation method and panel wiring practice.
-
RoHS compliance is not uniform across variants: the seed does not list a RoHS status; 3VA5111-5ED11-1AA0 and 3VA5111-5ED11-0AA0 are explicitly marked RoHS non-compliant. For equipment destined for regions with environmental regulations, compliant suffix options require verification before ordering.
-
Series and mounting are consistent: all listed parts are SENTRON series, lever-actuated, DIN-rail mounted, and boxed. These parameters do not drive differentiation among the eight listed MPNs.

Why 3VA5111-5ED16-0AA0 is similar: identical 1-pole, 110 A, lever-actuated SENTRON device with matching approvals and DIN-rail mounting; differs only in termination suffix convention, which governs lug type rather than electrical rating.
Why 3VA5111-5ED11-1AA0 is similar: same series, pole count, rating, actuator, and mounting; expands approval scope to include CSA and EAC but is marked RoHS non-compliant and omits VDE from its approval listing.
Why 3VA5111-5ED26-1AA0 is similar: identical electrical rating, series, actuator type, approvals, and mounting method; represents the two-pole variant within the same family code, enabling two-phase branch protection with the same interrupting rating.
Engineering Verification Checklist
- Confirm required approval agencies (CCC, CE, UL489, VDE) match the installation jurisdiction and equipment standard.
- Verify 110 A rating suits the calculated branch load with appropriate derating per applicable standard.
- Check conductor size compatibility with the termination style implied by the -1AA0 suffix.
- Confirm DIN-rail enclosure space and side-clearance requirements for the 3VA51 form factor.
- Confirm single-pole configuration is adequate for the ungrounded conductor being protected.
- Verify the interrupting rating (35 kA per the title reference) meets or exceeds available fault current at the installation point.
- Validate that no external tripping accessory conflicting with the lever actuator is required.
- Confirm product status "Active" aligns with procurement and lifecycle planning.
- Cross-check applicable coordination requirements if this breaker serves upstream or downstream in a selective coordination scheme.
FAQ
Does the 3VA5111-5ED16-1AA0 include an auxiliary contact? The catalog record does not list an auxiliary contact configuration; it specifies illumination as none and actuator type as lever only. No auxiliary contact presence or rating is noted in the on-record specifications.
What distinguishes the -1AA0 suffix from the -0AA0 variants in the 3VA51 series? The -1AA0 termination identifier indicates a nut-lug style conductor termination per Siemens SENTRON naming conventions. The -0AA0 variants (such as 3VA5111-5ED16-0AA0) use a box-lug or crimp-style termination. Both share the same electrical ratings and approvals.
Can the 3VA5111-5ED26-1AA0 replace the seed in a single-pole application? The 3VA5111-5ED26-1AA0 is a two-pole device rated at 110 A, sharing series, approvals, actuator type, and mounting with the seed. Pole count and physical width differ; replacement in a single-pole space requires panel re-evaluation and coordination verification. It is not a drop-in interchange.
