For a panel running warm, that 2 A drop at the top end is worth noting if you're loading the breaker near its nameplate. ## Breaking capacity — where it fits in a distribution scheme At 415 V, that's a healthy figure for a 25 A frame — it clears high-fault scenarios without needing a current-limiting upstream fuse in most industrial panels. Rated operating voltage is 415 V AC and 250 V DC; the DC figure covers battery-bank or DC-bus protection where the 2-pole series trip handles the arc. Dimensions: 70 mm deep, 50.8 mm wide, 130 mm tall. At roughly 2 inches wide, it occupies a single 2-pole MCCB slot in a SENTRON distribution panelboard or a 3VA/3VM mounting base. Front face carries IP40 protection — splash protection not guaranteed, but fine for a dry indoor enclosure. No trip indicator, no undervoltage release, no communication function — this is a straight thermal-magnetic breaker with no auxiliary electronics.","metaTitle":"Siemens 3VM1125-3ED22-0AA0 SENTRON MCCB, 25A, 76kA at 240V","metaDescription":"Siemens SENTRON 3VM1125-3ED22-0AA0 molded case circuit breaker, 2-pole, 25A rated, 76kA interrupting at 240V AC.

The 3VM1125 should mechanically fit the same panel cutout and bus-bar arrangement. However, the 3VA series uses a different accessory platform (auxiliary switches, shunt trips) — if the panel uses those accessories, verify compatibility before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1125-3ED22-0AA0","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/3VM1125-3ED22-0AA0 when reusing this data.
