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.","metaTitle":"Siemens 3VA2340-7JP32-0AA0 SENTRON MCCB, 400 A, 3-Pole, ETU5","metaDescription":"Siemens 3VA2340-7JP32-0AA0 SENTRON molded case circuit breaker, 400 A at 40 °C, 3-pole, ETU550 trip unit, 330 kA at 240 V.
