It carries an ETU320 electronic trip unit with an adjustable overload range from 600 A up to 4 800 A, so it covers a wide swath of feeder and main breaker roles without swapping hardware. ## Breaking capacity by system voltage This MCCB delivers 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. For most 400 V-class industrial distribution, the 187 kA figure covers high-capacity transformer secondaries and large motor control centers. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint that fits Siemens 3VA panelboard and switchboard mounting bases. ## Trip unit and protection design The ETU320 electronic trip unit is a line-protection design — it does not include ground-fault monitoring or undervoltage release as built. No communication function or voltage trigger is fitted on this variant. The trip indicator is not present, so fault indication relies on the breaker's handle position or an external auxiliary contact.","metaTitle":"Siemens 3VA2440-6HL32-0AA0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, ETU320 release.
