The 500 A rating holds flat from 40 °C through 50 °C, then derates gradually to 480 A at 70 °C. That thermal curve means the breaker can sit in a warm enclosure without losing headroom until the ambient climbs above 55 °C — useful for a panel near a furnace line or in a non-conditioned electrical room. The ETU350M release is a microprocessor-based overcurrent trip designed for motor protection: it includes phase-failure detection and an adjustable time-current curve that coordinates with motor-start inrush without nuisance tripping. ## Integration and footprint The IP40 front protection means it is splash-safe from the front but not sealed; install it in a panel with a door or cover for environments with dust or dripping water. Auxiliary contacts are included as 2 HQ switches, and the breaker ships with an undervoltage release (3VA9608-0BB25) pre-installed. No communication module or ground-fault monitoring is fitted on this variant — those are separate order options if the application needs them.","metaTitle":"Siemens 3VA2450-7MN32-0DC0 SENTRON MCCB, 500 A, 3-pole, Moto","metaDescription":"Siemens 3VA2450-7MN32-0DC0 SENTRON molded case circuit breaker, 500 A rated current, 3-pole, motor protection, ETU350M release, 330 kA at 240 V.
