The 415 V figure is the one you'll compare against your panel's prospective short-circuit current (PSCC) in a standard 400 V three-phase system. If your fault level at the breaker terminals is under 75.6 kA, this breaker holds. At 690 V the capacity drops to 11.9 kA — still enough for most 690 V industrial networks, but check your transformer impedance if you're close to that limit. The 240 V rating (121 kA) is typical for high-fault residential or light commercial subfeeds. At 55 °C it derates to 120 A, at 60 °C to 117.5 A, at 65 °C to 115 A, and at 70 °C to 112.5 A. The auxiliary switches can be wired into a PLC input to confirm breaker position.","metaTitle":"Siemens 3VA1112-4EF36-0DC0 SENTRON MCCB, 125 A, 3-Pole, Line","metaDescription":"Siemens 3VA1112-4EF36-0DC0 SENTRON molded case circuit breaker, 125 A rated continuous current, 3-pole, TM240 release, 121 kA at 240 V.
