The 80 A rating holds flat from 40 °C to 50 °C; above that it derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. For a panel running warm, that derating curve is the real selection gate — not the headline 80 A. Rated insulation voltage Ui is 800 V, and the operating range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C. ## Auxiliaries and release configuration No communication function, no phase failure detection, no ground fault monitoring, no voltage trigger. It is a pure line-protection device: thermal-magnetic, no electronics. That is the mechanical life for the switching mechanism — not the electrical endurance under load, which will be lower depending on the fault current it interrupts. For a main breaker in a distribution board that cycles infrequently, 15,000 operations is well into the service life of the panel. That 76.2 mm width is a 3-pole MCCB footprint — it occupies three 25.4 mm (1-inch) module spaces on a DIN rail or mounting plate. Verify clearance for the undervoltage release and auxiliary switch wiring before laying out the gland plate. The overcurrent release design is TM240 — a thermal-magnetic trip unit with a 240 A frame rating, but this specific breaker is factory-set for 80 A continuous. For DC network applications, the manufacturer directs to the 3VA device manual for switching power values; that manual is linked under Service & Support.","metaTitle":"Siemens 3VA1180-4EF32-0DH0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1180-4EF32-0DH0 molded case circuit breaker. 80 A rated, 3-pole, TM240 release.
