That's a high-interrupting rating — it clears serious fault energy without the arc climbing upstream. At 55 °C it's 120 A, at 60 °C it's 117.5 A, at 65 °C it's 115 A, and at 70 °C it's 112.5 A. If the panel runs hot — say near other breakers or a transformer — that derating curve tells you exactly what you can pull without nuisance tripping. No guesswork. The IP40 front protection means it's fine in a clean indoor panel; keep it out of washdown zones. It carries an undervoltage release (UVR) as standard — the auxiliary trip specified is 3VA9608-0BB24. If you need those, this isn't the order code. The 3VA1112-5EF32-0CA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.","metaTitle":"Siemens 3VA1112-5EF32-0CA0 SENTRON MCCB, 125 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1112-5EF32-0CA0 molded case circuit breaker, 125 A rated, 3-pole, line protection, TM240 release.
