Breaking capacity is 121 kA at 240 V, 75.6 kA at 415/440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. No undervoltage release or communication module on this variant, so no extra wiring for those accessories.","metaTitle":"Siemens SENTRON 3VA1340-4EF32-0AA0 MCCB, 400 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VA1340-4EF32-0AA0 molded case circuit breaker, 3-pole, 400 A rated at 40 °C, 121 kA breaking at 240 V.
