It uses an ETU350 electronic trip unit, so you get adjustable long-time, short-time, and instantaneous protection curves — not a fixed thermal-magnetic bimetal. That means you can coordinate selectivity downstream without swapping the breaker body. The undervoltage release (UVR) is integrated from the factory, which drops the breaker if control voltage falls below the dropout threshold — common in emergency-stop or undervoltage-protection schemes on conveyor lines or pump skids. At 55 °C it's 385 A, at 60 °C it's 370 A, at 65 °C it's 355 A, and at 70 °C it's 340 A — so if your panel runs hot near the top of the enclosure, you need to account for the drop. Interrupting capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. That 242 kA at 240 V is typical for transformer secondary main breakers in large commercial or industrial services; the 40 kA at 690 V still covers most 690 V motor circuits. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. No auxiliary contact block is included, so if you need a status feedback signal to a PLC or a remote trip indicator, you'll add one separately. Maximum power loss is 98.5 W at rated current — that's heat that stays inside the enclosure. For a panel with multiple breakers side by side, factor that into your thermal rise calculation to avoid nuisance tripping from ambient buildup.","metaTitle":"3VA2340-6HN32-0DA0 SENTRON MCCB, 400 A, 3-pole, ETU350","metaDescription":"Siemens SENTRON 3VA2340-6HN32-0DA0 molded case circuit breaker, 400 A continuous, 3-pole, ETU350 release, 242 kA at 240 V.
