It carries a rated continuous current Iu of 100 A across the full ambient range from 40 °C to 70 °C, no derating needed in a warm panel. The electronic trip unit is an ETU350M, which means you get adjustable overload and short-circuit protection curves plus phase failure detection — the phase failure detection flag is set to Yes, so it will trip on a lost phase, which is exactly what you want on a motor circuit to prevent single-phasing. Breaking capacity is voltage-dependent: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V. Those numbers tell you this breaker is built for high-fault locations — think transformer secondaries or large motor control centers where the available fault current is substantial. ## Motor duty and panel fit Rated motor-switching power is 30 kW at 230 V AC-3 and 55 kW at 400 V AC-3, so it covers a good range of medium induction motors on 400 V three-phase systems. The 3-pole design fits standard three-phase motor circuits. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — that width is the standard 105 mm frame size for this SENTRON 3VA2 series, so it occupies one 105 mm slot in a panel or switchboard. The front face carries an IP40 protection class, meaning tools or fingers won't reach live parts from the front, but the breaker is not sealed against moisture — it's for indoor panel mounting.","metaTitle":"Siemens 3VA2110-7MN32-0BB0 SENTRON MCCB, 100 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2110-7MN32-0BB0 molded case circuit breaker, 100 A rated, 3-pole motor protection with ETU350M release.
