That 800 A holds flat through 50 °C; at 55 °C it derates to 780 A, and at 70 °C to 722 A — so in a warm panel you still have solid headroom. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and 52.5 kA at 690 V, making it a strong choice for high-fault industrial distribution where you need the short-circuit rating to match the transformer size. The built-in auxiliary switch configuration is 1 auxiliary switch plus 1 trip alarm switch HP. If your BOM calls for a communicating breaker or a shunt trip, this isn't the variant; if you need a straight 800 A feed with a TM240 curve and a trip indicator, it fits. Dimensions are 320 mm high x 210 mm wide x 120 mm deep. The 120 mm depth is the key number for enclosure depth planning — it's a standard MCCB depth that fits most 400 mm deep distribution boards. Width at 210 mm means you need to check the busbar riser spacing and adjacent breaker clearance in a multi-breaker lineup. Rated insulation voltage is 800 V, operating temperature range -25 °C to +70 °C, storage from -40 °C to +80 °C. Max power loss is 240 W — factor that into your enclosure ventilation calc if you're grouping several breakers.","metaTitle":"Siemens 3VA1580-5EF32-0AG0 SENTRON MCCB, 800 A, 3-pole, 187","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0AG0 molded case circuit breaker, 800 A at 40 °C, 3-pole, 187 kA at 240 V.
