Power loss runs 19.2 W max at rated load — manageable in a closed panel but worth checking if you're packing breakers tight. ## Interrupting capacity — the real-world numbers The 121 kA at 240 V is the headline number, but the more useful figure for a 400 V class panel is 75.6 kA at 415 V. At 440 V it drops to 52.5 kA, and at 500 V or 690 V it holds at 11.9 kA. ## Thermal derating — what the 80 A means at your panel temp At 55 °C it derates to 78 A, at 60 °C to 77 A, at 65 °C to 75 A, and at 70 °C to 74 A. If your panel ambient runs 50 °C or below, you get the full 80 A; above that, factor the derate into your load calculation. That 76.2 mm width is a 3-pole frame — it occupies three 25.4 mm (1-inch) module positions on a DIN rail or panel-mount plate. ## What you get — and what you don't — in this variant It does not include an undervoltage release, ground-fault monitoring, a communication module, or a trip indicator. The basic switch supplied is 3VA10804ED360AA0. If you need undervoltage release or ground-fault protection, you'd step to a different suffix in the 3VA1080 family.","metaTitle":"Siemens 3VA1080-4ED36-0JC0 SENTRON MCCB, 80A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0JC0 molded case circuit breaker, 3-pole, 80A rated at 40°C, 121kA interrupting at 240V.
