It carries the ETU350M electronic trip unit with LSI protection — long-time (Ir adjustable 200–500 A), short-time (Isd 3–15 x Ir), and instantaneous (Ii fixed at 15 x In). The unit also ships with an undervoltage release (24 V DC) and a nut keeper kit, both factory-fitted. The ETU350M LSI curve is for motor protection: adjustable Ir matches motor FLA, Isd provides selectivity, and Ii at 15 x In clears hard faults. The undervoltage release drops the breaker below 24 V DC for emergency-stop chains.","metaTitle":"Siemens 3VA2450-5MN32-0BE0 Circuit Breaker, 500A, 55kA @ 415","metaDescription":"Siemens 3VA2450-5MN32-0BE0 IEC frame 630 MCCB, 3-pole, motor protection ETU350M LSI, 500A, Icu=55kA @ 415V.
