Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V, and still 187 kA at 500 V — that's enough for high-fault utility feeds or transformer secondaries where standard MCCBs would cascade. Phase failure detection is built into the release, so a lost phase on the motor feeder will trip the breaker rather than let the motor single-phase and burn. That's the difference between a plain feeder breaker and a motor-protection MCCB — the release watches for unbalance, not just overload. ## Sizing for motor duty — AC-3 power ratings Rated operating power in AC-3 duty (squirrel-cage motor starting, switching during running) is 11 kW at 230 V and 18.5 kW at 400 V. ## Panel fit — dimensions and IP rating That's a 4.1-inch wide footprint — three of these sit in roughly 315 mm of DIN-rail or panel-mount width. ## Environmental and electrical ratings Rated insulation voltage Ui 800 V, so it's suitable for 690 V systems (though the interrupting rating at that voltage is limited). Maximum power loss 10 W at rated current — negligible for panel heat budget.","metaTitle":"Siemens 3VA2140-7MN32-0BH0 SENTRON MCCB, 40 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2140-7MN32-0BH0 SENTRON molded case circuit breaker, 40 A rated continuous current, 3-pole, motor protection version with ETU350M release.
