The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V — enough headroom for most distribution panels feeding motor control centers or lighting circuits. The 125 A rating holds flat from 40 °C through 50 °C, then derates to 120 A at 55 °C and 112.5 A at 70 °C. That means in a warm enclosure — say a non-ventilated panel near a furnace line — you size the load at 112.5 A, not the nameplate 125 A. The 800 V rated insulation voltage (Ui) covers 480 V and 600 V class systems with margin. The interrupting ratings step down as system voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That 10.5 kA figure at 690 V is the limiting case — if your panel feeds a 690 V drive bus, verify the available fault current stays under that number. The 52.5 kA at 415 V is the typical European distribution level; it coordinates well downstream of a 65 kA-rated main breaker. ## Auxiliary and Trip Configuration The shunt trip (STL) is factory-integrated — no field kit to install. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth, fitting standard 3-pole MCCB panel cutouts.","metaTitle":"Siemens 3VA1112-3EF36-0JH0 SENTRON MCCB, 125 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1112-3EF36-0JH0 molded case circuit breaker, 125 A rated at 40 °C, 3-pole, line protection, 75.6 kA at 240 V.
