At 415 V and 440 V it still handles 154 kA, and at 690 V it drops to 17 kA, so the real-world SCCR depends on your system voltage. The 400 A rating holds steady up to 50 °C; above that it derates to 392 A at 55 °C and 367 A at 70 °C, which matters if the breaker sits in a hot enclosure or next to other heat sources. ## Integration and fit Dimensions are 248 mm high, 138 mm wide, 110 mm deep — standard 3-pole MCCB footprint for a 400 A frame. The undervoltage release is built in, so no separate UVR module to mount and wire. Insulation voltage rated 800 V, which covers most 480/600 VAC panels with headroom. The basic switch variant is 3VA13406EF320AA0, meaning the base breaker without the UVR is a separate order code if you need a spare without the release.","metaTitle":"Siemens 3VA1340-6EF32-0CH0 SENTRON MCCB, 400 A, 3-Pole, 220","metaDescription":"Siemens 3VA1340-6EF32-0CH0 SENTRON molded case circuit breaker, 400 A at 40 °C, 3-pole, 220 kA breaking at 240 V.
