That adjustable band means you can fine-tune the overload protection to match the actual load without swapping the breaker — useful when a motor or transformer draw is slightly below the frame rating. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V — numbers that put it in the high-fault category for industrial distribution. This is a line-protection design (not motor-protection), so the trip curve is shaped for cable and busbar protection. The breaker holds 250 A continuously up to 50 °C ambient. Above that it derates: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Max power loss is 48 W, which adds to the enclosure heat load. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard SENTRON 3VA frame size that fits existing 3VA panel cutouts.","metaTitle":"Siemens 3VA2225-5JQ32-0KH0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5JQ32-0KH0 molded case circuit breaker, 250 A adjustable, 3-pole, 187 kA at 240 V.
