That thermal curve matters if this lives in a hot panel next to drives or transformers. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V. Those numbers drop sharply above 500 V — 7.5 kA at both 500 V and 690 V — so if your line runs 690 V, this is not the high-fault unit you want. Footprint: 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). Comes with an undervoltage release (UVR) built in and two HQ auxiliary switches. The UVR means the breaker trips if control voltage drops — common for emergency-stop chains or safety circuits where loss of power must open the motor circuit.","metaTitle":"Siemens 3VA1180-6MH32-0DC0 SENTRON MCCB, 80 A, 220 kA at 240","metaDescription":"Siemens 3VA1180-6MH32-0DC0 SENTRON molded case circuit breaker, 3-pole, 80 A rated at 40 °C, 220 kA breaking capacity at 240 V.
