Rated continuous current holds at 32 A up to 50 °C ambient; above that it derates gradually to 28.8 A at 70 °C. That means in a warm enclosure — say a non-ventilated panel near a furnace line — you plan for the 30.72 A at 55 °C or 29.44 A at 65 °C, not the 32 A nameplate. Interrupting rating drops with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That 10.5 kA at 690 V is the number to check if the breaker feeds a 690 V drive or transformer primary — it is still adequate for most industrial installations where the prospective fault current at that voltage is under 10 kA, but verify against the utility's available fault current at the point of common coupling. ## Built-in auxiliary and shunt trip The integrated auxiliary trip module carries order code 3VA9688-0BL30, which is the spare part number if the shunt trip coil needs replacement without swapping the whole breaker.","metaTitle":"Siemens 3VA1132-3EF32-0HC0 SENTRON MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF32-0HC0 molded case circuit breaker, 32 A rated, 3-pole, 75.6 kA at 240 V.
