The Siemens 3VA1180-6GF42-0AA0 is a SENTRON molded case circuit breaker rated 80 A continuous with a TM240 thermal-magnetic overcurrent release, sized for line-protection duty in distribution panels. Four-pole construction handles three-phase plus neutral or double-pole DC switching; the interrupting capacity hits 220 kA at 240 V and still holds 154 kA at 415 V, so it clears high-fault utility feeds without cascading upstream. Rated insulation voltage is 800 V, and the thermal derating curve stays flat at 80 A up to 50 °C, then drops to 74 A at 70 °C — useful to know when the breaker sits in a warm enclosure next to other heat sources.
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — fits standard panel-mount cutouts for 4-pole MCCBs in that amp frame. Front-side IP40 protection keeps dust out of the enclosure interior during normal operation. Max power dissipation is 19.2 W at full load, which drives the internal temperature rise in a sealed panel — factor that into the enclosure thermal budget if grouping several breakers.
Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. No undervoltage release, no communication module, no ground-fault monitoring on this variant — it is a straight thermal-magnetic line-protection breaker.
