Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 19.2 W, which matters for thermal rise calculations in a multi-breaker panel. ## Auxiliary switches and shunt trip — what ships inside The auxiliary switches give remote status of the breaker position (open/closed); the trip alarm signals that the breaker tripped on fault, not manual operation. The shunt trip lets a remote pushbutton or PLC output open the breaker — useful for emergency-stop circuits or interlocking with a fire-alarm panel.","metaTitle":"Siemens 3VA1080-4ED36-0HH0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1080-4ED36-0HH0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 121 kA breaking capacity at 240 V.
