The interrupting rating varies with system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 415 V distribution board, the 32 kA SCCR gives solid headroom for most industrial fault-current scenarios without cascading upstream. ## Current derating over temperature Above that, it derates linearly: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The 4-pole design handles three-phase plus neutral in a single unit, saving rail space over separate breakers. ## Temperature range and storage The wider storage window matters for spares kept in unheated warehouses — the breaker can sit at -40 °C without damage, but must be above -25 °C to be energized.","metaTitle":"Siemens 3VA1080-2ED42-0KA0 SENTRON MCCB, 80 A, 4-Pole, 52.5","metaDescription":"Siemens 3VA1080-2ED42-0KA0 SENTRON molded case circuit breaker, 80 A rated continuous current, 4-pole, breaking capacity 52.5 kA at 240 V.
