Siemens SENTRON 3VA2340-7JP32-0AA0 — 400 A MCCB with ETU550
Breaking capacity hits 330 kA at 240 V and still holds 242 kA at 415 V and 440 V, so it handles high-fault utility feeds without cascading upstream. At 690 V the rating drops to 7.5 kA — still adequate for most 690 V motor branch circuits, but verify coordination with the upstream device if you're on a high-capacity 690 V bus. The breaker includes a communication function, letting it report status and trip events to a BMS or PLC over PROFIBUS or PROFINET.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON 3VA2 mounting plates and busbar systems. Maximum power dissipation is 96 W at rated load.
