The Siemens SENTRON 3VA1180-6ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 80 A continuous current on an 800 A frame, with a TM210 thermal-magnetic overcurrent release and line protection design. It carries no undervoltage release, no communication function, and no ground-fault monitoring — a straight thermal-magnetic breaker for standard feeder or branch protection. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V or 690 V. That 220 kA at 240 V is high — this breaker handles very high available fault currents at low voltage, typical for large transformer secondaries or industrial service entrances. At 690 V the 17 kA rating is still respectable for a 3-pole MCCB in this frame size. Thermal derating is flat from 40 °C to 50 °C at 80 A, then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If the panel ambient runs above 50 °C, the continuous load must be reduced accordingly. Insulation voltage is rated 800 V, operating range -25 °C to 70 °C, storage -40 °C to 80 °C.
Mounting and integration
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The 76.2 mm width is standard for a 3-pole MCCB in this class — fits a 3-module DIN-rail footprint or panel cutout. Depth of 70 mm is compact for an 800 A frame breaker; verify gland-plate clearance and door swing if panel depth is tight. Maximum power loss is 19.2 W at rated current. Account for this heat in the enclosure thermal calculation, especially if multiple breakers are ganged in a small cabinet.
