Short-circuit breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. Rated insulation voltage is 800 V, so the breaker is comfortable on 480 V and 600 V class systems with margin. The shunt trip release (STL) means you can wire a remote emergency-stop or supervisory signal to open the breaker without being at the handle — common in E-stop circuits or PLC-controlled load shedding. The 32 A rating holds flat from 40 °C through 50 °C. At 55 °C it drops to 31 A, and at 70 °C it is 30 A. If the panel ambient runs hot — say 50 °C inside a NEMA 12 enclosure with other devices — you still get the full 32 A. Above that, plan the load at 30 A to avoid nuisance tripping. Power loss is 10.6 W maximum at rated current. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall. The 76.2 mm width is a standard 3-pole MCCB footprint for this class — it fits the same DIN-rail or panel-mount cutout as other SENTRON 3VA frame breakers. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. That covers unheated warehouses and outdoor enclosures in most climates.","metaTitle":"Siemens 3VA1132-6EF32-0KA0 SENTRON MCCB, 32 A, 3-Pole, Shunt","metaDescription":"Siemens SENTRON 3VA1132-6EF32-0KA0 molded case circuit breaker, 32 A rated at 40 °C, 3-pole, TM240 release, shunt trip.
