At 55 °C it still carries 385 A, and at 70 °C it holds 340 A — so the full 400 A frame is usable in most ventilated enclosures without oversizing. Breaking capacity is 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 40 kA at 690 V — figures that cover most industrial service-entrance and distribution applications where high fault current is expected. ## Lifecycle and sourcing — active, quoted to order The 3VA2 platform is Siemens' mainline MCCB family, so documentation (datasheets, CAD models, UL/IEC certificates) is readily available from the manufacturer's support portal. No last-time-buy windows or phase-out notices are associated with this code. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for 400 A frames. The depth (110 mm) is shallow enough for most 600 mm deep enclosures with rear cable space; the 138 mm width means it occupies roughly 5.4 inches of DIN-rail or mounting-plate width per pole.","metaTitle":"Siemens 3VA2340-6HL32-0HH0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens 3VA2340-6HL32-0HH0 SENTRON molded case circuit breaker, 400 A rated continuous current, 3-pole, line protection with ETU320 release.
