That flat 125 A band across 40–50 °C means it holds its full rating in a warm panel without needing to oversize; the derate curve only engages above 50 °C. Breaking capacity is 53 kA at 240 V AC and 8 kA at 415 V AC — the 240 V figure covers most North American panelboard fault levels, while the 415 V number is the relevant one for 400 V-class European distribution. The 1-pole form factor (25.4 mm wide) fits standard Siemens panelboard slots; depth is 70 mm, height 130 mm. Mounts in a standard Siemens panelboard or loadcenter on the DIN-rail or direct-mount bus. The 25.4 mm width (1 inch) occupies one pole space. No trip indicator, no voltage trigger — it's a basic thermal-magnetic trip unit. Maximum power loss is 8 W, so heat dissipation in a densely populated enclosure is manageable.","metaTitle":"Siemens SENTRON 3VM1112-3ED12-0AA0 MCCB, 1-pole, 125 A, 53 k","metaDescription":"Siemens SENTRON 3VM1112-3ED12-0AA0 molded case circuit breaker, 1-pole, 125 A rated at 40-50°C, TM210 release.
