This curve is typical for MCCBs with a fixed trip — the magnetic break point is tuned for the lower-voltage, higher-fault-current scenario common in 240 V industrial distribution. At 690 V, the 17 kA rating still covers most motor-control-center bus faults. ## Thermal derating and continuous current Rated 80 A continuous at 40 °C through 50 °C ambient; above that, derate linearly to 74 A at 70 °C. The frame holds 80 A solidly in a 40 °C panel — no need to oversize for a warm enclosure unless ambient exceeds 50 °C. Power loss is 19.2 W maximum at rated load, which matters for heat buildup in a crowded panel. The 3VA1180-5EF36-0HA0 measures 130 mm high, 76.2 mm wide (3 inches), and 70 mm deep. That 3-inch width per pole is standard for 160 A frame MCCBs — it fits the same mounting footprint as other 3VA1 3-pole units, so a panel designed for a 3VA1110 or 3VA1010 will accept this breaker without drilling new holes or changing bus bars.","metaTitle":"Siemens 3VA1180-5EF36-0HA0 SENTRON MCCB, 80 A, 187 kA at 240","metaDescription":"Siemens 3VA1180-5EF36-0HA0 SENTRON molded case circuit breaker, 80 A continuous, 187 kA interrupting at 240 V.
