Breaking capacity at 240 V is 187 kA, at 415 V it's 121 kA, at 440 V it's 75.6 kA, and at 690 V it's 17 kA — that's high-interrupting capability for a compact 3-pole frame, meaning it can clear severe faults without upstream fuses having to open first. Rated insulation voltage Ui is 800 V, and the operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Front protection is IP40, so it's splash-proof from the front but not sealed for washdown; the rest of the breaker is open to the panel environment. It cross-references to the SENTRON 3VA family and is widely stocked across the supply chain. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — that's a standard 3-pole MCCB footprint for a 160 A frame, so it drops into most panel layouts that accept SENTRON 3VA breakers. Mechanical endurance is 15,000 operations.","metaTitle":"Siemens 3VA1180-5EF32-0AC0 SENTRON MCCB, 80 A, 3-pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0AC0 molded case circuit breaker, 80 A, 3-pole, TM240 release, 187 kA at 240 V.
