It carries an In of 500 A and uses the ETU350M electronic trip unit with LSI protection — long-time (Ir adjustable 200 A to 500 A), short-time (Isd adjustable 3 to 15 × Ir), and instantaneous (Ii fixed at 15 × In). That LSI curve is sized for motor starting inrush and coordinated downstream with contactors and overload relays per IEC 60947-4-1. ## Integrated accessories for panel wiring All auxiliary contacts are wired to the same terminal block, so the panel builder can land the remote trip and status signals without opening the breaker cover.","metaTitle":"Siemens 3VA2450-5MN32-0KJ0 Circuit Breaker, 500 A, 55 kA @ 4","metaDescription":"Siemens 3VA2450-5MN32-0KJ0 IEC frame 630 motor protection circuit breaker, 55 kA breaking capacity at 415 V, 500 A In, ETU350M LSI trip unit.
