It uses an ETU350M electronic trip unit with phase-failure detection, so it can discriminate between a genuine overload and a lost phase on a motor circuit. ## Interrupting and thermal performance The interrupting rating scales with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. Maximum power loss is 37.5 W, which matters for enclosure thermal calculations. ## Trip unit and auxiliary contacts Latching endurance is rated at 15 000 operations.","metaTitle":"Siemens 3VA2325-5MN32-0AJ0 SENTRON MCCB, 250 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0AJ0 molded case circuit breaker, 250 A rated continuous current, 187 kA interrupting at 240 V.
