The Siemens SENTRON 3VA1180-4EF42-0AA0 is a 4-pole molded case circuit breaker rated 80 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release.
Interrupting capability across voltage levels
The interrupting ratings step down cleanly as voltage rises: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For most 480 V panels, the 52.5 kA at 440 V is the relevant figure; derate slightly for the actual 480 V operating point.
At 55 °C it drops to 78 A, at 60 °C to 77 A, at 65 °C to 75 A, and at 70 °C to 74 A.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm) is standard for a 4-pole MCCB in this frame size — verify the mounting footprint matches your existing DIN rail or panel-mount adapter.
