The 125 A rating holds flat across 40 °C to 50 °C ambient; above that it derates to 114 A at 70 °C, which matters if the breaker sits in a warm enclosure near other heat sources. The 3VA1112-3EF36-0AH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a 3-inch wide, 5.12-inch high form factor that fits the standard SENTRON 3VA1 panel cutout. It mounts via screw-on lugs to a backplate or DIN-rail adapter plate; the 3-pole width is the same as other 3VA1 125 A frames, so swapping in a panel originally wired for a 3VA1110-5ED36-0AC0 requires no busbar or lug relocation — same mounting centers, same line/load connection pattern. ## Release and auxiliary configuration A mechanical trip indicator is built in for local visual fault indication.","metaTitle":"Siemens 3VA1112-3EF36-0AH0 SENTRON MCCB, 125 A, 52.5 kA","metaDescription":"Siemens 3VA1112-3EF36-0AH0 SENTRON 3-pole MCCB, 125 A rated, 52.5 kA at 415 V, TM240 release, 70x76.2x130 mm.
