The Siemens 3VM1150-5EE46-0AA2 is a 4-pole IEC frame 160 circuit breaker with a 50 A rated current and a 55 kA breaking capacity at 415 V (class M). The overload protection is adjustable from 35 A to 50 A via the TM220 thermal-magnetic trip unit, and the short-circuit protection is fixed at 10 x In (500 A). The neutral conductor is unprotected, meaning it passes through without an internal trip element — verify the downstream neutral is sized for the fault current or add a separate neutral protection device.
