This is a standard IEC 60947-2 device, so the 55 kA rating is the ultimate short-circuit breaking capacity — the maximum fault the breaker can clear once and remain functional afterward. The nut keeper kit noted in the description (for DC Power OEM in China) suggests the unit ships with hardware intended for a specific OEM assembly — verify the kit contents if you are integrating into a standard Siemens 3VA1 panelboard rather than a captive OEM build. The 3-pole configuration suits three-phase line protection for feeders, branch circuits, or downstream sub-distribution.","metaTitle":"Siemens 3VA1125-5ED32-0AA0-ZD00 Circuit Breaker, 25A, 55kA @","metaDescription":"Siemens 3VA1125-5ED32-0AA0-ZD00 IEC frame 160 breaker, 3-pole, 25A fixed thermal-magnetic, 55kA breaking capacity @ 415V.
