Its ETU350M electronic trip unit provides phase failure detection and a voltage trigger, making it suited for protecting motor feeders and other inductive loads in industrial switchboards and motor control centers. At 690 V the 3VA2450-7MN32-0JL0 still clears 52.5 kA, which covers most 690 V industrial networks. For a site electrical engineer building a selective coordination study, the 242 kA at 415 V means this MCCB can be the main or feeder breaker in a 400 V panel where the transformer secondary fault current is in that range, and its electronic trip unit allows adjustable I²t curves to achieve Type 2 coordination with downstream motor starters. The 3VA2450-7MN32-0JL0 measures 138 mm wide, 248 mm high, and 110 mm deep. It mounts into a standard Siemens SENTRON 3VA draw-out or fixed cradle; the 138 mm width is three pole spaces wide on a 45 mm per-pole pitch. The front IP40 protection means it is suitable for installation in enclosed switchboards where no water spray is present. ## Trip unit and auxiliary release details A shunt trip (STL) is integrated as the auxiliary release, allowing remote tripping from a PLC or emergency-stop circuit. Maximum power loss is 99 W, which should be factored into enclosure thermal calculations.","metaTitle":"Siemens 3VA2450-7MN32-0JL0 SENTRON MCCB, 500 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0JL0 molded case circuit breaker, 500 A rated, 330 kA breaking at 240 V.
