Breaking capacity hits 75.6 kA at 240 V, drops to 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V or 690 V — that 75.6 kA figure at 240 V is the headline number for high-fault industrial panels on 240 V delta or 240/120 V center-tap services. The TM240 thermal-magnetic release is tuned for line-protection duty (cable and busbar protection), not motor-starting curves; the 800 V rated insulation voltage gives headroom for 480/277 V and 600 V systems. ## Dimensions and integration — panel footprint At 70 mm deep, 101.6 mm wide, and 130 mm tall, the 3VA1132-3EF46-0AA0 fits standard 4-pole MCCB panel cutouts in the SENTRON family — the same footprint as other 3VA 4-pole units, so a panel laid out for a 3VA1110-5ED32-0AA0 will accept this breaker without rewiring the bus or drilling new mounting holes. Breaking capacity: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, 11.9 kA at 500 V and 690 V. Number of poles: 4. Overcurrent release: TM240 (thermal-magnetic, line protection). Rated insulation voltage: 800 V. Power loss: 10.6 W maximum. Storage: -40 °C to 80 °C. Front protection: IP40.","metaTitle":"Siemens 3VA1132-3EF46-0AA0 SENTRON MCCB, 32 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF46-0AA0 molded case circuit breaker. 32 A rated at 40 °C, 4-pole, TM240 release, 75.6 kA breaking at 240 V.
