Rated insulation voltage 800 V. At 415 V it breaks 52.5 kA, at 440 V it drops to 32 kA, and at 500 V or 690 V it holds at 11.9 kA — the same value, meaning the arc extinction limits are reached above 500 V. For a 480 V distribution panel with an available fault current of 25 kA, this breaker has 32 kA of headroom at 440 V (the nearest published point); at 500 V the 11.9 kA rating may be the binding constraint for 600 V class systems. ## Thermal Performance and Power Loss The 32 A rating holds steady from 40 °C through 50 °C; at 55 °C it derates to 31 A, at 65 °C to 30 A, and at 70 °C to 30 A — so in a warm panel near the top of a MCC lineup, expect 2 A of headroom loss. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that drops into Siemens SENTRON mounting bases and busbar systems without adapters. Front face IP40 protection.","metaTitle":"Siemens 3VA1132-3EF32-0AA0 SENTRON MCCB, 32A, 75.6kA at 240V","metaDescription":"Siemens 3VA1132-3EF32-0AA0 SENTRON molded case circuit breaker, 3-pole, 32A rated at 40°C, 75.6kA interrupting at 240V.
