It carries a motor-protection ETU550M trip unit with LSI protection (long-time, short-time, instantaneous) and a rated current In of 500 A. Overload protection is adjustable from 200 A to 500 A; short-circuit protection ranges from 1.2 to 15 times In for the short-time pickup, and 3 to 15 times In for the instantaneous pickup. The 500 A frame and adjustable overload (200–500 A) let you size it to a specific motor full-load current, not just a fixed rating. ## Deployment context This MCCB mounts in a switchboard or motor control center (MCC) via its busbar connection — typical for protecting large motors, feeders, or distribution branches in industrial plants. The undervoltage release provides automatic trip on loss of control voltage, a common requirement for safety circuits and coordinated shutdown sequences.","metaTitle":"Siemens 3VA2450-5MP32-0DH0 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA2450-5MP32-0DH0 IEC frame 630 MCCB, 55kA breaking capacity @ 415V, 3-pole, motor protection ETU550M LSI, In=500A.
