If it's 60 kA at the same voltage, you need a higher-rated frame or upstream current-limiting fuse — the SCCR at the equipment level must stay at or below the breaker's rating. In a crowded panel with multiple breakers side by side, ambient temperature inside the enclosure can easily hit 55–60 °C — so that 38.4 A or 37.6 A effective rating is the real-world limit, not the 40 A on the label.","metaTitle":"Siemens 3VA1040-3ED32-0DA0 SENTRON MCCB, 40 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1040-3ED32-0DA0 3-pole molded case circuit breaker, 40 A rated, TM210 release, 75.6 kA at 240 V.
