It carries a breaking capacity of 75.6 kA at 240 V AC, 52.5 kA at 415 V AC, and 32 kA at 440 V AC, so it handles high-fault scenarios typical of industrial distribution panels without cascading upstream. The TM210 trip unit provides fixed thermal and magnetic settings — no adjustment dials — which keeps the part simple for a fixed-load BOM line where the engineer already knows the cable and load current. ## Thermal derating and ambient temperature profile At 55 °C it derates to 122 A, at 60 °C to 120 A, at 65 °C to 117 A, and at 70 °C to 114 A. That's a gentle slope — about 0.6 A per degree above 50 °C — so a panel running at 60 °C ambient still carries 120 A continuous. ## Mounting dimensions and panel fit The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. Width of 76.2 mm (3 inches) matches the typical 3-pole SENTRON slot; depth of 70 mm means it clears most 200 mm deep enclosures with room for wiring gutters.","metaTitle":"Siemens 3VA1112-3ED32-0AA0 SENTRON MCCB, 125A, 3-Pole, TM210","metaDescription":"Siemens 3VA1112-3ED32-0AA0 SENTRON molded case circuit breaker, 125A rated at 40°C, 3-pole, TM210 thermal-magnetic trip unit.

The difference is the trip unit: the -3ED32 carries a TM210 thermal-magnetic release, while the -5EE32 carries an electronic trip unit with adjustable settings. If the panel wiring and load current match the 125 A fixed setting, the swap is a straight mechanical drop-in — no rewiring needed. But verify the interrupting capacity requirements at your system voltage: the -3ED32 delivers 75.6 kA at 240 V and 52.5 kA at 415 V; the -5EE32's ratings may di"},{"question":"What compliance documentation does Siemens provide for 3VA1112-3ED32-0AA0?","answer":"As a current SENTRON series product, Siemens publishes a full compliance package including the CE declaration of conformity, UL/CSA recognition (IEC 60947-2), RoHS and REACH declarations, and the product manual with installation and trip-curve data.
