The 3VA1 frame mounts on DIN rail in a standard panel enclosure. The nut keeper kit for DC Power OEM in China indicates this variant was kitted for a specific OEM assembly; the keeper secures the breaker's terminal nuts during transport and panel vibration.","metaTitle":"Siemens 3VA1112-3ED42-0AA0-ZD00 Circuit Breaker, 125A, 25kA","metaDescription":"Siemens 3VA1112-3ED42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 125A, Icu=25kA @ 415V.
