That makes it a general-purpose distribution breaker, not a motor-protective device; if you need adjustable magnetic or electronic trip, you'd look at the 3VA1 with an ETU release instead. The breaking capacity figures tell you where this breaker can safely interrupt a fault without welding contacts or rupturing the case: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. For a 125 A frame, those are high-interrupting ratings — the 187 kA at 240 V covers most North American secondary-side fault levels, and the 121 kA at 415 V handles heavy industrial distribution in IEC territories. The temperature derating is published per the datasheet: the breaker carries its full 125 A from 40 °C through 50 °C, then begins to step down — 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. ## Auxiliary and release configuration The integrated auxiliary trip is order code 3VA9688-0BL30, which is the factory-installed accessory that makes the shunt trip and aux switches work together on the same mechanism. ## Mechanical integration and environment The 76.2 mm width (3 inches) matches the standard 3-pole MCCB footprint for a 125 A frame — it fits the same mounting base and bus-bar spacing as other SENTRON 3VA1 breakers in this current class. Latching endurance is 15,000 operations.","metaTitle":"Siemens 3VA1112-5ED32-0HH0 MCCB, 125A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0HH0 molded case circuit breaker, 125A rated, 187kA breaking at 240V.

The difference is in the release and accessories: the -5ED32-0HH0 carries a TM210 thermal-magnetic release with a shunt trip and 2 aux + 1 alarm switch, while the -5EF32-0CA0 uses a different release and auxiliary configuration. If the panel wiring relies on the shunt trip and aux contact arrangement, verify the terminal assignments match before swapping — the mechanical fit is the same, but the control wiring may need adjustment."},{"question":"What is 3VA1112-5ED32-0HH0's listed depth?","answer":"The depth is 70 mm, measured from the mounting surface to the front of the breaker."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-5ED32-0HH0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1112-5ED32-0HH0 when reusing this data.
