That 800 A rating is the same across 40–50 °C, so you get full capacity in most ventilated enclosures without oversizing. Breaking capacity is the headline here: 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 52.5 kA at 690 V. For 415/440 V systems the 121 kA still covers most industrial service entrances. It's a 3-pole breaker with line protection design, meaning it's set up for feeder or main protection in a distribution panel, not motor protection — no overload class or adjustable thermal curve for starting inrush. The shunt trip (STL) on this variant lets you remote-trip from an E-stop or PLC output without a separate undervoltage release. ## Auxiliaries and integration No communication module onboard, so if you need remote monitoring over PROFIBUS or Modbus you'll add the 3VA communication kit separately. Dimensions are 320 mm high, 210 mm wide, 120 mm deep — fits standard SENTRON 3VA fixed-mount or plug-in base.","metaTitle":"Siemens 3VA1580-5EF32-0HC0 SENTRON MCCB 800A 3-Pole, 187kA a","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0HC0 molded case circuit breaker, 800A rated at 40°C, 3-pole, 187kA breaking capacity at 240V.
