It carries a continuous current of 400 A at 40 °C, with no derating needed up to 50 °C — at 55 °C it still holds 392 A, and at 70 °C it delivers 367 A. The interrupting capacity is 154 kA at 415 V AC, 220 kA at 240 V, and 121 kA at 500 V, with a 17 kA floor at 690 V.
Insulation voltage rated at 800 V, so it's comfortable in 690 V systems.
The breaker includes a trip indicator and voltage trigger.
Rated 400 A continuous at 40 °C, 3-pole, with a breaking capacity of 154 kA at 415 V AC. Insulation voltage is 800 V. Dimensions are 248 x 138 x 110 mm.
This part is sourced through independent distribution channels and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an inquiry for a firm quote on your volume.
No — the 3VA1340 is a 400 A frame (248 x 138 x 110 mm), while the 3VA1110 is a smaller 100 A frame. The footprint, busbar spacing, and mounting hole pattern differ. Panel redesign or adapter kit is required.
Siemens SENTRON 3VA series MCCBs carry IEC 60947-2 certification. Standard documentation includes CE declaration of conformity and manufacturer's declaration for RoHS/REACH compliance. UL/CSA listings vary by specific variant — verify with the factory datasheet for this exact order code.
