3VA51 Series — Alternate Pole Configurations
The 3VA51 family shares the same frame, termination style, and thermal-magnetic trip mechanism across pole counts. Up to three additional alternates exist within the same MPN prefix range.
Single-Pole Alternative
3VA5112-5ED11-1AA0 mirrors the seed in all respects except pole count — it is a one-pole variant, still rated 125 A, DIN rail, lever-operated, and carries identical CCC/CE/CSA/EAC/UL489/VDE certifications.
Three-Pole Alternatives
3VA5112-5ED31-1AA0 and 3VA5112-5ED32-1AA0 extend the series to three poles at 125 A per pole. Both use the same lever actuator, DIN rail mounting, and box packaging. Certification coverage for the "-1AA0" suffix includes CCC, CE, CSA, EAC, UL489, and VDE; the "-2AA0" suffix omits CE and CSA in favor of CCC and UL489 only.
