It carries the ETU350 electronic trip unit, a line-protection release that handles overload and short-circuit discrimination without the thermal drift of a bimetal. Breaking capacity runs from 330 kA at 240 V down to 7.5 kA at 690 V, so the interrupting rating you spec depends on the system voltage the breaker sees. ## Breaking capacity — what the voltage-dependent ratings mean for coordination At 240 V the 3VA2325-7HN32-0AA0 interrupts 330 kA; at 415 V and 440 V it holds 242 kA; at 500 V it drops to 187 kA; at 690 V it is rated 7.5 kA. For a 480 V panel, the 242 kA figure at 440 V is the closest reference — the actual SCCR at 480 V sits between the 440 V and 500 V ratings, so coordination studies should use the lower 187 kA bound at 500 V to stay conservative. The ETU350 release allows adjustable short-time delay for selective coordination downstream. Footprint is 138 mm wide by 248 mm tall by 110 mm deep. That 110 mm depth (4.33 in) is the dimension that matters for enclosure depth clearance — the breaker projects forward from the mounting surface, so the backpanel-to-door clearance must accommodate it plus wiring space. Width of 138 mm (5.43 in) fits a standard 3-pole MCCB cutout; height of 248 mm (9.76 in) is the vertical envelope.","metaTitle":"Siemens 3VA2325-7HN32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-7HN32-0AA0 molded case circuit breaker, 250 A continuous, 3-pole, ETU350 release.
