That SCCR range means it can sit upstream of a 480 V motor branch or in a 690 V industrial feeder without worrying about cascading faults. ## Current ratings and thermal curve The TM240 thermal-magnetic release holds 80 A from 40 °C through 50 °C; at 55 °C it derates to 76.8 A, then 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The adjustable response time tr max is 1 s, so you can fine-tune the long-time pickup to ride through inrush on a motor start. The 3VA1180-3EF36-0AE0 measures 130 mm high, 76.2 mm wide, 70 mm deep. IP40 on the front keeps dust out of the nameplate and trip window; the rest of the body is open to the enclosure, so don't use it in a washdown zone without a separate cover. ## Auxiliary contacts and releases This MCCB ships with 4 auxiliary switches HQ — that's the high-quantity variant for signaling breaker status to a PLC or alarm annunciator without adding external relays. If you need remote trip or earth-leakage, you'll add the separate accessory modules; the frame accepts them.","metaTitle":"Siemens 3VA1180-3EF36-0AE0 SENTRON MCCB, 80 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1180-3EF36-0AE0 SENTRON molded case circuit breaker, 80 A rated current, 3-pole, breaking capacity 75.6 kA at 240 V.
