Interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream. Dimensions are 248 mm height, 138 mm width, and 110 mm depth — mounts into standard switchboard or panelboard cutouts for 400 A frame MCCBs. The 3-pole construction fits three-phase distribution. Maximum power loss is 63.5 W, so factor heat dissipation into enclosure sizing if grouping multiple breakers. ## Trip unit and auxiliary components The overcurrent release is the ETU320, an electronic trip unit with LSI protection (long-time, short-time, instantaneous). The shunt trip (STL) design allows remote opening via a control voltage.","metaTitle":"Siemens 3VA2440-5HL32-0HL0 SENTRON MCCB, 400A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0HL0 molded case circuit breaker, 400A rated, 187kA interrupting at 240V.
