The interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, which covers most industrial service-entrance and feeder applications on 480 V systems. At 690 V it still breaks 11.9 kA, enough for some European motor circuits. ## Panel fit and power loss The 3VA1140-3GF46-0AA0 measures 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole MCCB that fits standard distribution panelboards and switchgear cubicles. Maximum power loss is 10.8 W, which matters for thermal calculations in sealed enclosures.","metaTitle":"Siemens 3VA1140-3GF46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1140-3GF46-0AA0 SENTRON molded case circuit breaker, 40 A rated, 4-pole, 75.6 kA interrupting at 240 V.
