The 80 A rating holds flat from 40 °C to 50 °C, then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Plan the load accordingly; the breaker won't trip early, but the continuous current you can pass is the derated figure, not the nameplate 80 A. The two auxiliary switches give status feedback (open/closed/tripped) back to the control system. No undervoltage release on this order code, so if you need UVR for a machine-start interlock, this isn't the variant. That 19.2 W is the heat you need to vent in a sealed enclosure — not trivial if you're stacking several breakers in a row.","metaTitle":"Siemens 3VA1180-4EF36-0KC0 SENTRON MCCB, 80A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1180-4EF36-0KC0 molded case circuit breaker, 80A, 3-pole, line protection.
