Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that cover high-fault utility feeds and large transformer secondaries without needing a current-limiting upstream device. The 3-pole, line-protection version carries a rated insulation voltage of 800 V and mounts in a standard panel footprint (70 mm deep, 76.2 mm wide, 130 mm tall). ## What the interrupting ratings mean for panel coordination For a site electrical engineer building a selective coordination study, those numbers tell you the 3VA1180-6EF32-0KA0 can sit directly downstream of a transformer with a high short-circuit capacity — no need to oversize the main breaker just to protect this feeder. Above that, the continuous current derates stepwise: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. For a panel OEM wireman packing breakers into a sealed enclosure, those derated figures are the ones to use for conductor sizing and thermal coordination — not the 80 A nameplate.","metaTitle":"Siemens 3VA1180-6EF32-0KA0 SENTRON MCCB, 80 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1180-6EF32-0KA0 SENTRON molded case circuit breaker, 80 A rated, 3-pole, 220 kA at 240 V.
