It's a 3-pole unit rated 80 A continuous at 40 °C, with a thermal derating curve that holds 80 A through 50 °C, then steps down to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C — useful to know when you're packing breakers into a warm enclosure. Breaking capacity is the headline here: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. Physical footprint is 130 mm high, 76.2 mm wide, 70 mm deep — a 3-pole MCCB that fits standard Siemens 3VA panel mounting.
Integration Notes
Designed for line protection — that's the standard MCCB role for feeder circuits, not motor protection (no overload relay class or adjustable thermal curve here). The trip indicator and voltage trigger are built in, so you get a visual flag and a signal output on trip without extra wiring. That covers most indoor panel environments, including unheated warehouses in cold climates, as long as the panel stays above -25 °C during operation.
