Rated 250 A continuously at ambient temperatures up to 50 °C without derating — above that the thermal curve steps down: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That means the breaker holds its full rating across typical panel internal temperatures; derating only becomes a factor in hot enclosures or adjacent to high-wattage devices. Interrupting capacity is declared per voltage level: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. ## Built-in Auxiliaries and Communication Communication function is present on this order code, enabling integration with higher-level monitoring or energy management systems. The basic switch variant underlying this assembly is 3VA2225-5JQ32-0AA0. Maximum power loss is 50.5 W — a figure to account for in enclosed panel thermal calculations, especially when multiple breakers are ganged in a single enclosure. ## Physical Fit and Environmental Range Dimensions are 86 mm depth, 105 mm width, 181 mm height — a standard 3-pole MCCB footprint that fits SENTRON 3VA mounting bases and common DIN-rail or panel-mount adapters.","metaTitle":"Siemens 3VA2225-5JQ32-0DH0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-5JQ32-0DH0 molded case circuit breaker, 250 A rated, 3-pole, with communication function and undervoltage release.
