That means in a 40 °C panel environment it carries the full 400 A without headroom games; if your enclosure runs hotter, the breaker self-protects by reducing its continuous rating, so the load side must be sized for the derated value. Interrupting capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, 11.9 kA at 690 V. ## Lifecycle and sourcing — active, quoted to order ## Panel integration — dimensions and mounting The breaker measures 248 mm high, 184 mm wide, 110 mm deep. Four-pole frame, so it occupies the full width of the 3VA 400 A platform — no reduced neutral pole. Power loss at full rated current is 92.1 W maximum. That's the heat the breaker dissipates into the enclosure — factor it into your panel thermal calculation, especially if the MCCB is mounted alongside other high-current devices.","metaTitle":"Siemens 3VA1340-5EE42-0AA0 SENTRON MCCB, 400 A, 4-Pole, TM22","metaDescription":"Siemens 3VA1340-5EE42-0AA0 SENTRON molded case circuit breaker, 400 A continuous, 4-pole, TM220 release, 187 kA at 240 V.
