The Siemens 3VA1180-6EF32-0AE0 is a 3-pole SENTRON molded case circuit breaker rated for 80 A continuous current at 40 °C, with a TM240 thermal-magnetic overcurrent release. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker clears high-fault energy without cascading upstream, which matters when the line feeds a motor control center or a secondary distribution panel where available fault current is high. The thermal curve holds 80 A flat through 50 °C, then derates to 76.8 A at 55 °C and 72 A at 70 °C.
Mounts on a DIN rail or direct panel surface — the 76.2 mm width and 70 mm depth fit a standard 3-pole MCCB footprint, so it drops into existing SENTRON or 3VA-series cutouts without re-drilling the gland plate. Comes with 4 auxiliary switches HQ (high-quantity) built in, which gives you status feedback for PLC inputs or alarm annunciation without adding a separate aux block.
